Hi,

I want to use an image as default in a gallery based on the condition if there are any attachments included in the item. If yes, then I want to show the first image from this attachment. If no attachment has been added to the item, I want to use a default image.

I gave the default image an OnSelect property = Set(varBild; No Attachment). Second is the image name uploaded to PowerApps.

I tried to implement the following Image property in the gallery:
If(IsEmpty(First(ThisItem.Anlagen).Value);varBild;First(ThisItem.Anlagen).Value)

But the default image is not showing?! Where is the issue here? I would be thankful for support!

I believe the issue you are having is you used semicolons instead of commas. Try replacing it with this code:

If(IsEmpty(First(ThisItem.Anlagen).Value),varBild,First(ThisItem.Anlagen).Value)

P.S. If you aren't picky about the image that's in the field when there's no attachment, PowerApps has an item called "SampleImage", which just puts their default image in the field. It could save you some time and space on coding.

@cmitchener No, the syntax is fine. We use ";" instead of ",".
The issue is something else.

I see, my mistake. What I would try is temporarily replacing varBild with SampleImage to see if that will work, then that will at least tell you if the variable is correctly loading. You could also try adding apostrophes into the Set function to make it like so:

Set(varBild; 'No Attachment')

Let me know if this will work

@cmitchener same issue with SampleImage. No picture shown in gallery. Apostrophes were already used in the Setfunction.

Interesting; maybe try using only First(ThisItem.Attachments).Value to see if that works. The app could be having trouble finding the data
