I have that plugin on my 2.91 installation. In addition to all my playlists for all the CD's I have, I created little HTML files that display the album cover in JPG format. All that is saved on the local machine. So, I can have a playlist like the following:
\Covers\Eagles - Hotel California.html
\mp3\Eagles\Eagles - Hotel California.mp3
\mp3\Eagles\Eagles - New Kid In Town.mp3
...and so on. What the plugin does is take the HTML file (or just about any graphics file format) and open it in the minibrowser, then proceed to play the files. I created them in HTML originally so I could place the image centered in the browser window, which couldn't be sized infinitely like you can in Winamp 5.
In the skin I'm building now, I have a small 200x200 area dedicated to the media library display. But, the only thing I'd like it to do is pop an album cover JPG in there when the playlist is loaded, like the plugin above.
IE is the current browser but my JPG's are associated with Paint Shop Pro.
If I use the plugin above with WA5 it causes the behavior described. The media library seems to loop over and over again, attempting to display the graphic, and the player never gets to the MP3 files.
