Additional features, settings, or issues not covered by specific Microsoft Teams categories
Hi @Ming
Although your setup involves SharePoint as the data source and the app is accessed through Microsoft Teams, the behavior you described is related to how the Power Apps gallery renders the images, this would be best handled by the Power Apps (Power Platform) community rather than a Teams-specific forum.
At this point, I recommend posting your question in the Power Platform (Power Apps) community, where specialists can review your scenario in more detail and provide more targeted guidance. Microsoft Power Platform Community Forum
This forum is dedicated to Power Apps topics, so you’re more likely to get focused assistance from moderators and community members who regularly work with and support Power Apps scenarios.
Apologies for redirecting you to a different community as the members of the posted category focus on users with Microsoft 365 and Office. concern and have limited knowledge about Power Apps, so to get a quick and better assistance, we redirect you in the correct way.
Thank you for your patience and understanding, if you have any other questions or need further assistance, feel free to ask.
