I just uploaded a new patch to
http://bugzilla.gnome.org/show_bug.cgi?id=133459, that "fixes" these
"issues" :-) (uses gnome-vfs and gdkpixbufloader and loads only files <
200kb).

I don't know much about this... I only saw the screenshots of muine on
gnomedesktop.org and read that it searches for cover.jpg in the
mp3-directory. Since I thought that this is cool idea, I implemented it
for rhythmbox.

I think it's not really a Problem, as long as its documented in the
faq/help of rhythmbox. Another option would be to make the icon
clickable and connect it to a fileselector that lets the user select a
image manually. The file would then be copied to the directory of the
mp3 as "cover.[jpg|gif|png|etc.]" Another option would be to store the
uri for the cover in rhythmdb...

I'll have a look at the muine source-code. Sounds very interesting, but
I'm not very familiar with web-services. The important thing here is
imho the legal issue and it needs to be sure that the location/interface
for retrieving the images doesn't change, otherwise stuff will be broken
most of the time.

Not yet, but I will have a look at it :-)
