Haha, thanks! I'm really glad you like my formatting I'd be extra-glad if more people used it :D
Unfortunately, Smogon doesn't allow HTML at all, (I unsuccessfully appealed to that a while back, HERE) so the only option is to host the HTML elsewhere, like Google Sites (like I did). You can then use an online service or a program to convert the processed HTML to an image, but the easiest way is to just take a screenshot of the webpage and crop the images in your image editor of choice. Host the images on a site like Photobucket and then you can use standard IMG code to put the images in posts. It sounds like a lot of work, but it's really not. The whole process takes about three minutes if you've got your Pokemon's info already typed up.
