How to remove outlines surrounding the images when viewing files as thumbnails in the Blender file browser?

There are outlines surrounding the images when viewing files as thumbnail in the Blender Browser, how do I remove them?

Figure1

And if possible, is there a way to remove the logo that shows the file type?

I don’t think the outline or icon can be removed, unless you change the Blender code.

I don’t mind, I have no problem using programming even though I am a beginner

The code for drawing the file browser is here:

If you like it better without that border (with images of varying proportions) consider submitting a patch. Just make sure to include some screen capture caparisons to help make your case. I’d remove the little “image” icon at the bottom left as well.

If you get stuck, feel free to contact me.
