You have to put them in as a link to a photo saved somewhere else online. I upload all of my atv pics to my facebook account. Then when I want to enter an image in a post, I use pic language to enter it.
1.) upload picture(s) to a photo host online (like I said, I use facebook)
2.) find that picture in your online account, right click on it, choose preferences, and highlight and copy the http://
3.) then type your post and when you come to the place you want to enter your picture type [img]pastethehttp:// you copied in step two[/img]
This will allow the picture to show up as large as it is in the place you have saved the photo online. You can also use this to create larger signature pictures.
