I finally buckled to ask a question. Long story short, I ended up reinstalling windows XP on my machine and was putting in the latest Foobar2000 and setting it up with a nice theme and adding in all the updated components I could remember I had before (it wasn't intentional to reinstall windows, stupid router

)
Anyway, I'd originally started using Columns UI when I went and found this reallllly nice theme for the default one that I adored and put in. Well, the album art didn't change display no matter what I did. I'm not a scripter by any means and I don't understand the strings of code I see other than 'that works, that doesn't do anything, THAT is bad' after something happens. I messed and messed, but it wouldn't pick up the image files.
Then I noticed a link pointing to the Columns UI one and I went 'doh, stupid me, go get the RIGHT ONE if you're using default layout!'. This didn't change anything; in fact, putting in the latest version (2.7.1 from
http://cherans.bol.ucla.edu/fooplugins.html ) made it worse. The Album Art in preferences disappeared entirely o.O So now there's nothing to fix and it only ever shows that Microsoft music image or no image at all, even though I have a default.png in the components directory of foobar. Yes, the version number says it needs 9.4 instead of 9.5, but it sounded like people got it to work with 9.5.
Help? Maybe I'm not doing this right, which is entirely possible and more than probably likely, since I don't understand what any of those codes mean, either in this thread or others.
