Runtime error when uploading

When uploading I've been getting this runtime error - file does not exist message when trying to post from pivix, any clues on why this happens?

I believe it's because you're using a source like this:

i1.pixiv.net/img51/img/jyudo_fu/35756894_big_p10.jpg

When you should use:

http://i1.pixiv.net/img51/img/jyudo_fu/35756894_big_p10.jpg

If you don't use a full valid url, the site doesn't know to download from it instead of trying to use the file you give it (none, hence the "file does not exist").

Oh so that's what it was thanks for the info.
