I, and I’m sure many other Local Guides, would like to know how-to!
Hello @AdamGT
Understand your frustration, as I did that exercise recently.
Here are the answers to your queries.
To do that, I sorted the photos on the number of views.
Then, I opened the first one & went on adding captions by scrolling horizontally. We can access twenty photos at a time through the horizontal scroll. That allows reviewing also by moving back & forth.
Once complete, scroll that vertically & take the next set of twenty numbers.
The exercise becomes frustrating occasionally as once you come out of a session, the pointer again goes back to the top.
Nevertheless, after completing that exercise, I could locate the private photos by comparing the captions through in automated manner, as described in another post.
Hi friend @AdamGT
You are absolutely right at your points, I do agree
Thank you for sharing a problems with us!
Hopefully it will be solved by the time…
By the way did you see a post of me at Travel topic, i am missing you there 
Hello @AdamGT
Nice catch. I didn’t notice my photos of every place that I’ve also a review on it, don’t have respective caption! This is strange.
Not sure from when this issue started but seems I should go long down and check one by one to add a caption by phone which is so hard. I tested to add/edit caption on some photos (those have also review) and it works. Still no way for the web version.
@C_T ,
Your idea is problematic for those people like me that use desktop or laptop computers that do not run MS Windows. I use a Mac most of the time. I do not think that is an option with Apple computers besides the phones.

Thank you all for your comments and @C_T for you proposed solution. We write quality reviews, add quality photos and then end up with poor quality “Photo 1 of n” type captions which I believe has a major negative impact on the quality of our reviews and photos!! Review photos need proper descriptions to explain the photos and provide useful information to Maps users, and especially for accessibility reasons for those relying on screen/text readers. I have suggested this before in the Idea Exchange but sadly Google did not manage to implement the ideas in time so I was hoping that someone had a practical work around. As you yourself have so aptly described, your solution @C_T is nothing short of “painstaking”. Phones are cumbersome to use for volume activities, have small real-estate, small and difficult keyboards to use, the current location jumps to the top is also very frustrating especially when working on a volume number of photos. It’s painstaking on phones and we still don’t have a desktop solution! In the absence of a Google solution, I was hoping that someone would know of a simple procedure for both phone and desktop!
@C_T can you please give me the link to your post you mention in your point 2.
@AdamGT ,
I might know a program that will let you work on a Windows based computer. Ricoh Theta (app) costs but might let you. Here is a link. https://theta360.com/en/support/download/ I do not like copying URLs online. I found this one a minute ago. I hope it helps if you give it a try. I am not associated with the app or company.
I did not propose any solution on how to captioning on a Desktop @Androoh .
I have said it clearly one has to do that on a phone, tenaciously.
Nevertheless, you will find abundant literature on the net regarding how to run Android apps on Windows PC or Mac. I made mention only. Maybe some enthusiast has already adopted that!
Further, the ones using Chromebooks are already enjoying the amenities available on a phone in a bigger format. Thus, many possibilities exist if there is a wish.
Thanks @Androoh for the link. Do you need to have a Ricoh Theta to use the app? Have you tried this yourself and if o what steps do you take to upload photos with captions to Maps?
Thanks for the query @AdamGT
Here are the links to the two posts.
The second post is in Marathi. However, I have ensured that the English translation remains faithful to tell what I wanted to say.
*Interesting topic, I’m coming here to learn @AdamGT *
Something is really flakey! Over the last few days I have been adding some Maps reviews and always follow the same procedure:
Some of the reviews end up with the correct descriptions/captions on their photos and others don’t. Some reviews have some photos with captions and other photos don’t !!! It’s just intermittent. Sometimes it works, sometimes it doesn’t 
This has been a problem for at least 4 years!!! With so much said about accessibility and with the growing importance of assistive technology such as screen readers that convert text to speech or braille notation for people with visual impairment, I just find it hard to believe that we’ve had this problem for so many years @sonnyNg can this issue be looked at?
I experienced that phenomenon too @AdamGT
Further, I observed a reverse happening also. Some of the captions updated through Maps were visible in Google photos.
However, the behaviour is erratic. Some photos from the Google photos collection maintain a one to one relationship with the ones uploaded to Maps but many do not.
In that context, I remember one post saying one need not delete a photo from Maps for a minor modification. Do that in Google photos and the one visible in Maps will also update.
However, as said earlier, we can’t expect this rigid correlation for every photo and thus instead of adding captions in Google Photos, it’s prudent to do that in Maps only.
It is just so erratic @C_T . What we have is just so unpredictable, time wasting, frustrating, untitled photos is so unprofessional and a lost opportunity …You say instead of adding captions in Google Photos, it’s prudent to do that in Maps only, but what are the steps you take to do this? Do you add photos from Google Photos and then edit the photos to add captions? I cannot see any way of retrospectively adding or editing photo captions/titles on Windows desktop! Adding captions shouldn’t be a difficult procedure!
I did the addition through the following steps @AdamGT
Anyway, we have to start at the top.
When we add captions, these do not sync with the server immediately. If we come out & open the photo again, the caption wouldn’t be visible.
It may take a day or so to sync & then we perceive that we forgot to add a caption! However, the captions remain there in place while we are in a horizontal scroll.
I did that leisurely completing around a hundred & odd numbers in one session. Thus to cover the 1900 photos, It took three weeks.
Though you are looking for a solution on the desktop, it would be impossible to manage as it is.
Loading the photos on a desktop becomes resource-hungry & slows down beyond a certain point.
That doesn’t happen on the phone.
Thus, along with enabling of captioning, we would need filtering the photos over a specified date range. That would limit the count of photos getting loaded into the memory.
However, as per my guess, the programming team wouldn’t be committing resources to modify the web version of Maps to such an extent & then that would continue to remain a distant dream.
Very painful procedure but will try it @C_T . With so much said about accessibility and with the growing importance of assistive technology such as screen readers that convert text to speech or braille notation for people with visual impairment, I just find it hard to believe that we’ve had this problem for so many years
@AdamGT ,
I gave information before researching. I am not sure if that requires the camera to be the same brand in order to work. I wish to be able to edit photo spheres on my laptop before uploading too. I actually contacted the maker of the app. I have not heard back yet. I will share what I learn one I do.
@AdamGT ,
I learned part of what you asked. The answer is that the RICOH THETA app will edit photo spheres on a desktop or laptop computer. However, the camera must be a Ricoh Theta camera. Otherwise, you just attempt the undoable. I know how to edit photo spheres in Adobe Photoshop. However, that caused Google Street View to reject to attempted uploads. He does not know if Google Street View will accept edited photo spheres. I spoke with somebody on the phone. That is a Google Street View question. I might get one of those cameras if I am able to upload after editing. I do not know how to best learn the answer. You might not see a reply with an answer from me.
Hi @AdamGT I have the same problem (sadly no perfect solution). It would be a very good thing if Google would make captions available on desktop too.
There is a way to add captions to photo’s when uploaded from desktop. If you use a program that let you add caption to the EXIF maps will display that.
If you want to do it in retrospective or do some changes for now you have to do on the phone app.
Thank you for this post I do hope Google will make it possible to add captions in the desktop version.
Greetings, Erik
