will imagemagick handle all the bigger pictures?

Hi,

I know there is a problem with gd2 image toolkit that it will fait to resize maybe 10% of all the pictures that are over a certain size and also that are over a certain size in resolution. This issue seems to have been resolved in the recent php distribution, but we are running on php4 and were not sure it would be a good idea to change to php5.

Is imagemagick more solid regarding bigger pictures? I'M looking for a solution to handle almost every picture size that users can throw, at least going to high resolutions like 2000 and + pixels... Should I try to change to imagemagick??

Thanks
