Hello Woodjointer,
To post pics, first of all you want the pictures sized down to a reasonable size, somewhere around 600 pixels wide. The form will display wider pictures, but then they have scroll bars. There are many ways of resizing pictures, for example, photoshop, paint shop pro, etc... If you need something quick and easy to resize pictures, I suggest Fast Image Resizer
http://adionsoft.net/fastimageresize/After you have your pictures resized, start a new topic and click on "Additional Options" near the bottom. This will give you a browse button where you can browse for the images on your computer and attach them. When you are finished, click the Post button and you should be set.
Hope my instructions make sense. Now lets see that contraption!
