Power Platform Community Forum Thread Details

I tried several solutions to solve this issue without result and I’d like to discuss them with you.

Task: Build an app to make a query in a Sharepoint file library to filter, and then show, tif image files in a gallery.

Attempted solutions:

Flow: query using the SP connector ‘Get images (only properties)’. Problem: only files in the parent folder are detected (nested folter is set to true).
Flow using ‘HTTPS request to SharePoint’. Problem: I obtain all metadata I need, but the image control inside the gallery remains blanck because they are tif images.
I decided to use the same method of Delve to make preview (thumbnails). I have concatenated the file link, obtained before, to use this API:

https://******.sharepoint.com/sites/STM/_layouts/15/getpreview.ashx?path=https://*****/sharepoint.com/sites/STM/Documents/Images/myFolfer/MyFile.tif.

Result: Fantastic. The images appear. Turn of events, it works only in Powerapps Studio. Not in mobile android or Ipad powerapps app. The same behaviour if I open the image directly with Chrome browser: In the laptop it works, not in the mobile browser (403 forbidden).

4. I read in the Powerapps Community to add a new column in the SP library to create the thumbnail:

Name: Thumbnail
Type: Hyperlink
Hyperlink Type: image

The thumbnail appear in the SP library and if I copy this link in the image control, the tif image appears both in Powerapps Studio and in the mobile app.

Problem: when i get the metadata with Flow, this field, containing the thumbnail link, it’s not reported.

I tried to analize the link generated in the Thumbnail field but it’s impossible to decrypt.

Just an example 😂:

""https//northeurope1mediap.svc.ms/transform/thumbnail?provider=spo&inputFormat= JPG&cs=fFNQTw&docid=https%3a%2f%2f******.sharepoint.com%3a443%2f_api%2fv2.0%2fdrives%2fbmpAxlNj5LEKP_6dG876oG8XYKjcux3FNiLGeBmXOboItnJ8qgjlbRoroVWXgUSrh%2fitems%2f01IB5COKGHAR6HMIE6HBBLYKAUVI3JJKKT%3fversion%3dPublished&access_token=eyJ0eXAiOiJKV1 ………………………….&width=800&height=800""

Maybe if I decript this link could be the solution?

Sorry if I’ve been very long but they are several days that I spend on this problem.

Many thanks

Daniele
