Hmm.. It seems that the thumbnails script is now using more memory than what’s the allowed limit in your server.. It’s strange though as there has been no change to thumbnails generating code in v0.5 comparing to v0.4.1.. Have you tried small JPG images?
There is slight change actually though.. Before the thumbnails script always set the memory limit with ini_set() to 10mb or something, I have changed it so that if the limit in the server is already above 10mb, it won’t set it.. but if ini_get() doesn’t work in your environment, it might fail I guess..
You could ask your server host that can you do your own php.ini and increase the memory limit. I know that currently the image processing scripts take a lot of resources, but this issue will be addressed at some later stage..

I had the same issue. I backed up the maxigallery table, dropped it, and did a fresh install. Everything seems to be working fine now. It was frustrating me for a while but the problem seems to be solved.
