I’m just going to reopen this, because I haven’t got an answer to all my questions.
Yes I see you saying that you have gone trough this a 1000 times, but that shouldn’t stop you from helping.
In the ‘Understand GD Library’, you show how an image can use 900kb of memory.
But the images I’m trying to re-size only takes up 3,30MBytes of ram each.
But I have 17.98 MByte of ram at my disposal.
Why can’t I even make a thumb to one of them?
