Attaching photos to classified ads

How do I put Photos in classified ads?

I am not a "computer person", and I have a Mac. I have some photos on my desktop that I wish to put in my classified ads. But, when I'm filling out the ad form and get to the part that deals with photos, it asks me for the "image URL". How do I find an image URL for an image that is on my desktop?

HELP!

After you have filled out the information on the first page, hit "continue" at he bottom of the page. Then, where it asks for the name of your file, "Browse." THis will take you to the files in your computer, where you locate the one you want to upload, and click on it.
