If the pictures are on your computer, create a new thread like you did this one but in the clocks area and then click on the button below that says "Manage Attachments."
With that window open click the "browse" button and find the pictures on your computer. Select a picture and press "upload." You can do that up to 10 times if you have that many pictures.
Then you can click on the "submit" button and your request and pictures will be posted on the message board.
If you want to comment on each of the pictures individually, you can use the paper clip icon above the edit window to select each picture and insert it into your message (after you have them uploaded). Any you don't insert will go in a box at the bottom of your message.
