go to imageshack.us. upload the picture there. It'll resize it and also provide you a thumbnail forum code so you can post it small here and when someone clicks it it'll take them to the bigger picture.
You have to relink the "url=" link to go directly to the image otherwise it takes you to the imageshack website with your picture in the middle. Which is fine I guess.
There are other websites too but I like imageshack.us
I'd love to see how you did what you said!
