The File Chooser portal now works as expected, but it has a minor usability issue. The default filter is JPEG Image (*.jpeg) when the standard is to use PNG for custom artwork. It would be more usable if the File Chooser defaulted to PNG Image (*.png) or even better if it used All Files (*)

Steps for reproducing this issue:

1. Attempt to set custom artwork for a game
2. Browse to your image location

Result:

The image doesn't show up because the filter doesn't allow PNG images to show up by default

Expected:

The images should show up without changing the filter.
