Could it be the dimensions? Wonder if the panoramic sizing somehow throws off the watermark placement.

But they are much smaller, that image has about 25mpix.
Where is your hosting, can you increase php memory?

I'll try another big one.

25 mb with watermark,

I increased my memory already last time.


memory_limit = 32M
max_execution_time = 30     ; Maximum execution time of each script, in seconds
max_input_time = 60   ; Maximum time each script may spend parsing request data
memory_limit = 128M      ; Maximum memory a script may consume (16MB)
upload_max_filesize = 50M
post_max_size = 50M

This one is a bit smaller, maybe few bytes below limit. If you cant increase memory_limit above 128M, try to deactivate some plugins for processing time.

Processing works fine.

I will reduce it to 24mb and try again
