Normally I use imagecreatefromjpeg() and then getimagesize() , but with Firefox 3 I need to go round this different. So now im using imagecreatefromstring() , but how do I retreive the image dimensions now?

Answer 1

imagesx()和imagesy()函数似乎也适用于使用imagecreatefromstring()图像。

Answer 2

ah yes! i just found the answer on the internet a second ago :)

for those who still interested :

$image = imagecreatefromstring($img_str);
$w = imagesx($image);
$h = imagesy($image);
