And it works for me when that link is planted in the captions. I can go to any of the subsequent images in the album, and if I click on that link in the caption, I'm returned to the first image (the map of Australia).
ETA: Correction - the link is working only intermittently. Not sure why....
ETA: When the link fails, it takes you to the next image, rather than the first. When that happens, a quick F5 refresh actually makes it work. Something is being cached.
Thanks, this sheds some light on it. The links are treated as "inline" instead of "inline-block", which makes them harder to target. The skin tries to spot if a link was clicked but inline rendering makes the link areas the tightest possible. With "inline-block" the link targets are rectangular with paddings added, therefore making the hotspot area larger. Add this CSS to Settings / Site / Custom code / CSS:
