I am new to this site for selling stuff. I need some help on putting a photo or two in the ad. I could not find any link or tool to add a photo to the ad?

If you already posted it just reply with GO ADVANCED and then you can add photos when you scroll down you'll see the options

I got him fixed up. You can edit the existing post and click Go Advanced to add photos.

WHERE DO YOU START TO PUT IN A CLASSIFIED AD??

Click the Classifieds link at the top black bar on any page. Then click into the section there that best fits the items you want to sell. Then click the Post New Ad button at the top left of that page.
