fatal error

Hello,

when I try to change the standard size (width and height) from 640 x 480 px to another size I get the following error message:

Fatal error: Allowed memory size of 67108864 bytes exhausted (tried to allocate 24 bytes)

How can this problem be solved? I have no idea how to allocate more memory in your script.

Many thanks.
