hmm..
The images dont seem to be at the url you have set for the UBB:
http://www.ctfisherman.f2s.com/ubb/ Perhaps the images never where uploaded, try it again. Or perhaps CuteFtp created ghost files of the images, cause there where some ftp errors while uploading.
Just try upload them again, i think it will work <img src="https://www.ubbcentral.com/boards/images/graemlins/smile.gif" alt="" />
