first you have to upload a free service like http://photobucket.com/

the reason is, this site has a limited upload space, so you will only be able to add 1-2 pictures at most


once you have them uploaded at photobucket

if you are viewing the thumbnails view of your pictures then just move you mouse over the pic you want and it will expand to show 4 links,
you will want to copy the Direct Link



then you will click this on this site to input it



if you are on the full screen viewing on photo bucket the links will be on the left side of the screen



Hope this helps

feel free to ask questions


also after adding the pics to the upload site, file them how/where you want them before adding them here, because if you move the picture on photobucket then it will no longer show up here,
