You can't link to a picture on your own computer unless it is a dedicated server... online and available to internet browsers.

But this site allows you (encourages you in fact) to upload and post your picture right here.

Press "Go Advanced" (In the section just below the text box you write in is a section of additional options.)

Press "Manage Attachments" (A pop-up window appears. Make sure you allow pop-ups on your browser, or at least for this site.)

Press "Browse" and you get a standard windows box that lets you navigate through your folders. When you get to the picture you want to upload, select it.


When you finish selecting your picture(s)...

Press "Upload" then complete whatever you want to say in the text box and
Press "Submit"
