Comment 3 for bug 1324142

Hmmm... I guess it'll need to happen as part of the category renderer template, so the scope can nominate a preferred fallback image. The rest of it (making sure the fallback image is displayed when album art or some such can't be retrieved, or substituting a default fallback image if the scope hasn't specified one) is up to the shell.

I can work on this next week, if you like. I don't think it'll be difficult. I left this alone mainly because the bulk of the work could be done by the shell already. All it needs to do is display *something* when a request to retrieve artwork fails. Allowing the scope to specify a custom fallback image is just icing on the cake…

Cheers,

Michi.
