Problems with random block

I installed the random block linked to in this forum in my php Nuke 6.5. I got it working sorta. The picture shows up, but it's not in the borders of the block. It's above where the block should be and in the borders it says "There isn't content right now for this block." http://sexybear.orgHere's a link to what I'm talking about. Does this mean that my thumbnails are too big to use or something? How would I go about fixing this problem. TIA.

Oh, and one other thing how can I get it to link to gallery embedded in phpNuke rather than just the picture in the gallery when you click on the random picture.
