I wrote an answer to the first question there.
I’ll answer my own question. The function “imagecreatefromjpeg()” are a part of the gd-module to apache. This module does not come with jpeg support out of the box, you need to add a argument when you compile apacke. So if you get this error you need to activate jpeg supoprt in gd, and if you don’t controll the apacke installation, talk you or hostmaster.
A quick fix is to use png images and not jpeg, but this has some disavantages.
I get the same error now – I really like the look of this plugin, and I think it would work really well with my needs. If I only could fix this problem.
Is the plugin dependent of some other plugin? Where’s the imagecreatefromjpeg() gone?
