after you get the pics onto your computer, say in your my documents folder just do this....go to www.photobucket.com and if you dont have an account, get one...if you have one then upload your pics
They will upload onto photobucket...then after you see the pic displayed on your album page, copy the "IMG" link and just paste it into a post...the pics wont have to be uploaded onto the site and will just show up in IMG format...
