Hi - have you checked your path to the images directory? You can do this by going to your control panel and clicking the "DB, Paths & URLs" link under Master Settings. Click the "Paths & URLs" tab, and it will show you the relative URL to the images directory. Make sure that it matches the absolute URL to the main directory - for example:
Absolute URL to Main Directory:
http://laurie.infopop.cc/ubbthreads65b1Relative URL to Images Directory:
/ubbthreads65b1/images
If those don't match up, your images will not show up. Since it seems that you uploaded it correctly and set the proper permissions, this is the first place I'd look.
