37I 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 😂:
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
