I assume you meant to ask: "How do I upload pics whenever I post an ad PLEASE?"

To answer the question: When you click "New Topic", click "Additional Options" below the area where you type the information. There you will see the option to upload pics from your PC.
Upload each pic, and post the ad...
You're welcome!

PS: I find that pics uploaded this way take a LONG TIME to open when clicked while pics hosted on a media hosting website such as Photobucket open instantly. Is anyone else experiencing this??
