Sweet, I'm running a fresh install of ss 2.3-r67085 with the updated image gallery 0.6a2. Lots of improvements!
I think this is mostly css stuff - I plan on taking a look - but there are a couple problems when viewing an album. At least on my machine on FireFox 3.0.4.
Attached is a jpeg that the following comments refer to.
A. These little squares link to the 34th image and I have no idea why.
B. & C. The image gallery's 'gallery' tab is unmodified and says 30 per page, 6 images per row. Here the 7th image is being cut off, and the rest of them are nowhere. Likely CSS - I will investigate.
D* On multipage galleries, the show all button would be nice to have as an option for the public.
E. (not shown) - Just a reiteration of the request for the lightbox views to span the entire album rather than just the current page.
Hope this helps! All in all, great work! I'm sure lots of us really appreciate it.
