Seems to be a problem when sharing an image, if you have looked at several photos from a member and then share say the 3rd image you view, it seems to share the 1st image you viewed. Hope that makes sense, tested with a couple photos and had same issue.
This small annoying issue has followed Clickasnap ever since the beginning and I have ranted about it before; If I scroll through the most recent pictures on the site and click one to look at the picture and then go back to the list of recent pictures, I will land on a completely random place toward the beginning of the list. I can imagine this is too annoying for most people to bother looking at more pictures. There used to be this workaround by right-clicking the picture and opening in a separate window, but that doesn't seem to be possible anymore.
