note 25674 added to function.imagejpeg

I need to predict the file size of an image before saving it in the database. The only way I found is to save the image in a temp file with ImageJpeg() and checking it's size with FileSize() but I think it isn't elegant at all. I've read all the JFIF related stuff but I didn't find the way to get the adequated quality factor in a lower lever and more efficient manner. Did anyone found a better solution for this problem? -- http://www.php.net/manual/en/function.imagejpeg.php http://master.php.net/manage/user-notes.php?action=edit+25674 http://master.php.net/manage/user-notes.php?action=delete+25674 http://master.php.net/manage/user-notes.php?action=reject+25674
