That is quite possible. Doesn't IMP use the 'gd' library to generate
thumbnails? or it is gd who east all that mem?

You probably mean this one: http://bugs.horde.org/ticket/?id=3808
I am not so sure that's it - this is about displaying thumbnails instead of
linging them, and as long as they are not displayed, they probably don't get
processed. Or am I wrong and should I fill new report, or add comment to
this one?

Thank you.
