I need help!!

I just bought a digital camera and I took some good pics of my friends kitties. I want to show them to everyone but I don't know how!! I know I can make them as an attachment.jpg...but I want them to appear right on my message about them. Am I confusing or what?
A quick reminder...I am a computer idiot....

Help would be greatly appreciated:D

Phred has a whole tutorial posted: see here !

you put the disk that the pics are on, into the computer, then on the bottom of the page, where it says browse, pick which pic you want to post, then click on submit reply. let me know if that works ok? I hope I explained it right!:)
