I made this post a while ago, and I've been busy revising for my exams since

but I had another look at it today, and I found out what I was doing wrong; using the alpha channel in the code, when I didn't need to.
this is how its looking now:
CODE
$imageabs2(%width%,%height%,,,,,,,$replace(%path%,%filename_ext%,folder.jpg),nokeepaspect)
$imageabs2(%width%,%height%,,,,,,,C:\Program Files\foobar2000\background images\image2.png,nokeepaspect)
Pic:

as you can see I made my image in 1024x768 size in photoshop, a bit too big.
I was wondering how I can get both the album art
and the glossy image, to fit the window
even when it's resized?
(I figured it would be better to make a larger image, and have foobar scale it down to fit the panel, than to make a smaller image, and have foobar scale it up, losing quality.)
p.s. thanks all for the help
