adding pictures to your posts

Hey... when you click New Post, you get a little Microsoft Word-style editor (font, bold, italic, etc) to enter the promotion. Toward the right end of those icons, there's a little photo icon, looks like a polaroid of some mountains and sky. Click that to add an image.

then you can Browse to look through your computer for the file, and then Upload Image.
