I have an PowerApp that allows users to take pics from and upload them to a SharePoint Image Library. When I try to show a gallery of the images, I can't seem to get the thumbnails to appear. It works fine while editing in the studio, and when playing the app from my PC, but it won't work anywhere else. I tried it on a user's computer, in Teams, and on mobile(android tablet and iPhone). Everything works fine except the images. Here is what I've tried so far:

ThisItem.'{Thumbnail}'.Large
- This was in an image control
- The image didn't even show in the studio
ThisItem.'Link to item'
- Image control again
- This works in studio and on my PC, but not in Teams, mobile, or client's PC
"<img style='border:1px solid #ddd;width:150px;height:135px;border-radius:4px;'src=" & ThisItem.'Link to item' & ">"
- This was an html text control
- This works on my PC and in studio, but shows a broken link image anywhere else.

I would appreciate any help with this, it is frustrating me to no end.

Hi @PowerNewb ,

Firstly if you want to show these on mobile devices, the only way is ThisItem.'{Thumbnail}'.Large as below

We display tens or thousands of photos on iPads and various Android devices with the code below.

I assume the Items of the gallery are based on the SharePoint Library?

Please click Accept as solution if my post helped you solve your issue. This will help others find it more readily. It also closes the item. If the content was useful in other ways, please consider giving it Thumbs Up.

Hi, Warren! The items in the gallery come from a Sharepoint Picture Library.

I'm wondering if this is the issue, and I should be using a list instead?

Hi @PowerNewb ,

Yes I see the problem now - Picture Libraries were discontinued some time back (and were quite difficult to integrate with Power Apps) - you need a Document Library (which you can also store images in - they are just files).

There are about 40,000 photos in the Document Library in the screen shot in my post and it works very well on both PCs and mobile devices.

I switched to a Document Library and it works fine now. I wish I asked on here sooner, because this was driving me batty!
Thanks so much for the help. And thanks for putting so much work into your blogs, they've been extremely helpful for a new powerapps user.
