@Jackzhao88 ,

How do you retrieve images / where do you store them / how big is your data source?
I have experienced similar issue with 8000+ rows of data. But this typically resolves when data source is refreshed.

What's the image property in the gallery? Is it just ThisItem. ... or do you manually LookUp from your picture folder based on ThisItem data??

If you are using SharePoint List as the database, change authoring version of the app and publish it again. The SharePoint connector of power apps is unstable recently. I got the same problem last week. All thumbnail options were not working.

Here is how to downgrade the authoring version

Select Settings.

Select Support and review your existing Power Apps Studio version for the current session.

From the list of available authoring versions, choose the version that lower than the current version, and then select Reload + apply version.

Hi:
refer to below grab, only 3 versions available in the list, and current one already the lowest version, and how I can find more versions?

@Jackzhao88 ,
Instead of absoluteUri can you try use .Value ?

I had the same problem.
.Value is too slow compared to .AbsoluteURI, especially when the organization network is not great. So, in a web browser I prefer to use .AbsoluteURI instead.
