Barry,
I believe that you are referring to the "more" link beneath the Recent and Random picture block at the left of a Member's photos that only works for one change of pictures. The best way to look at a Member's Album contents is to click on the first thumbnail that is shown and then use the icons at the upper right corner of the picture frame to more forward or back in that Album. The center icon in that trio allows you to see a slide show of the pictures where you set the time delay.
Hope this helps.
