minor function syntax error...  did not appear to prevent functionality in previous versions, but should now be more correct

1.0 commit of imagefield_gallery, includes some minor admin usability improvements with a couple of accompanying css sheets.

hook_nodeapi fix, I was overwriting the entire array, now I'm just re-writing the #value and leaving the rest of the array alone.

Initial imagefield2 and Imagecache2 integration.  Additionally some minor usability fixes, as well as css generation fixes.
