In the last weeks several users report a failure of NextGEN Gallery. All of the users are using a web hosting of 1&1, current environment is : Apache/1.3.34 Ben-SSL/1.55 PHP/4.4.8
These users are not able to generate thumbnails (the script suddenly stopped) or get a memory failure message. The phpinfo() returns a memory_limit of 40 MB, normally enough for a 1600x 1400 resolution in a WordPress environment.
Thanks to Nana Torres, I’m able to debug this on a 1&1 web server and after 5 hours I found that imagecreatefromjpeg() stopped if you require more than 20 MB. This happened very early , when you uses a larger images. UPDATE : See FAQ
You can test this on your machine, with the attached script. If you see at the end a “*** SCRIPT END ***” your are not having the troubles…
Download 1&1 Test script
Simple PHP script
Update : See comment of Philip D. , PHP5 seems to do the work…
