Image upload - temp dir not found?

[eluser]#1313[/eluser]
Ah, i see. This time the problem was (most likely) caused by the dimensions of the picture (~4500x3000px). I resized it to 3000x2000, and the upload was successful.

Can somebody explain to me, is this behavior related to image_lib? I think so, because i did some image manipulting tasks with such huge pics on the same server before without CI, on bare PHP.

And the image_lib error messages do really need a punch in the head.

ps. don't ask why i am dealing with these pictures with the web server and not the photoshop =/
