I haven't bothered to upload to Videokarma in years. I just use postimg.org or imgbb.com. and just hotlink the pics in my post using [img][/img] tags.
Either of them are fast and you don't need to sign up, and can resize to a forum friendly size at the same time as upload . 1024 X 768, 640 X 480 ect.
Give it a try. It's fast and easy.
