I have my album art window occupy damn near fullscreen. Therefore, most 600x600 art is too lo-res for my +27" screen (with intent to get a larger one) and, unless there is no other size available (rare), I use 1000x1000 minimum and occasionaly have both front & rear combined images. All my art is embedded with MP3tag app.
HOWEVER, today as I was preparing the screen captures I noticed a serious issue. Not sure if it's me or WACUP. WACUP has very poor resolution displayed and is quite inferior to the actual image file. As a test I opened Winamp on the same folder for comparison. Winamp does not have this flaw. Original art images are 2000x983. Thoughts?
