Go to my pictures, right click on the picture and it should give you the option to resize it. Choose the option "small" if it isn't already selected. It should then show up in a seperate part of "my pictures" with the same title and the word (small) after it... as long as it's jpg, it should load onto here, don't forget to embed it in the post, it's easier viewing that way.

Hope that works, I'd like to see it.
