On the cover-art tab of a release (e.g. http://test.musicbrainz.org/release/b705dcee-a011-4bf0-abf2-4c4d9d586e9e/cover-art), once we have zoom on a image, we should be able to navigate to other cover art, still in zoom mode.
thickbox allows to do that very easily, you just need to
Give each link element the same rel element and value. (Example: rel="gallery-plants")
And we could also add the types in the picture legend as well (most needed if we can fgo prev/next pic :
<a rel="mb-caa" title="Front, Sticker, Obi" href="fullpic.jpg">
I thought of another idea so this ticket rocks even more.
In the sidebar's covert art, we can put all other pics as hidden a-rel-title-href-but-without-img.
So that, even if we only show the cover art, once clicked we can still watch all the pics without having to go to the specific Cover Art tab.
