I have the same effect when i try to watermark png pictures over 2.5MB Filesize.
The entire Picture gets a blue background exept the watermark image area.

With files under 2.5MB its working well.
Any idea how to solve that?

I use Version 1.8

Best Regards,
Sandro

That's a huge image size for web use. PHP GD won't deal with that very well.

first, don't use alpha levels on that sort of job, it forces PHP to do per-pixel processing. inefficient.

second, allegedly, imagemagick is much better at optimal image processing, if you need to do such huge stuff, it's probably a better subsystem to use.
