Can't watermark images

[tipsuli_]

I have problem with watermarking. My gallery worked just fine until now. I can't upload new images or batch add new images if watermarking is on. I can't watermark in admin tools.

I updated my gallery and I even installed it again from the scratch, 'cos I couldn't upload images. I have now new settings and I can add images and I just noticed that everhing works just fine unless you want to watermark images.

When I try to watermark in admin tools it just goes to blank page (http://mysticdiaries.net/galleria/util.php?t=173328202#admin_tools) and image files gets somehow "corrupted" or something. They dissappear or something. They don't show anymore.

Sorry I can't explain exactly what I mean 'cos my english sucks, but hope you understand what I mean.

What exactly happens when you try upload new images and watermarking is enabled in config?
