yes, you can upload your image here in this topic, or you can go to the photo expressions section, which is all about photos!
since it doesn't look like this site does attachments, you'll have to upload your images and link to them here. here's how:
go to a free image hosting web site, like
http://www.photobucket.com;
follow the instructions on uploading an image, then when you have, find the label that says IMG. copy the string of text that is next to it;
whenever you post, paste that jibber-jabber wherever you want the image to go, and it's on the page!
hope that helps!
