Here's how to post an image:

Go to Google Images and search for whatever subject of pic you need and include 300x300 in the description.

For example: I want an image of a dog. I would put this in the search section: Dog 300x300

Once the images come up you still need to hover over them because even though you put 300x300 you'll still get images of dogs in smaller/larger sizes.

Once you find the 300x300 image you want you click on it.

Then you right click on it and on the pop-up menu you select "copy image address".

Then you go to your partner's profile and go to the comment section.

You will then add this format: Exclamation point, left bracket, right bracket, left parentheses, then paste your image and add the right parentheses.

Gah - I'd love to join this swap but I've tried everything and can't figure out this image thing! Grrr!
