Lightning Man, there is no need to use a photo service. Your pictures are on the disc in files, most likely in jpg format.
Once the disc is inserted in your computer, you should know its device name (e:// or whatever). You can either copy the pictures to a directory (My Pictures is the common one) on your hard drive, or upload right from the disc.
To do so, go to reply, then click on GO ADVANCED. When the new screen comes up, type whatever you want and click on MANAGE ATTACHMENTS. Then use BROWSE to locate the picture file, either on your hard drive or on the disc, and it will upload to the site. Once your picture(s) - up to 4 - are uploaded, close the window.
