Re: Finding the height of a JPG in pixels using PHP

<snip from "Andrew Brampton" andrew@bramp.freeserve.co.uk> You can use getimagesize on a jpg file to read its size, so either save the jpg in MySQL to a file and then do a getImageSize, or before you place the jpg in to the database read its size and store its dimensions with it in the db. </> I disagree with Andrew. In my humble opinion, I don't think you need to duplicate information. Before you decide, have a better viewing of the problem. Not a good solution for me. I know little about JPEG files, but I know they have a HEADER. This header may contain the value (binary, o' course) you need, and even more info than you think. :) So, search a for JPG file's spec before you continue. Very easy to find. After you know about the files you work with, you have to know how to tell PHP to do what you want to do. I am not a good person to tell you that, as I am such a newbie to PHP. I can only tell that this would be "pisso chocka cake" in assembly. (VERY VERY easy =) <snip from "Phil Schwarzmann" phil.schwarzmann@filanya.com> I have JPG files stored as binary in a MySQL database. I am displaying the JPGs on the screen and also want to know the height (in pixels) of the JPG. </> Another solution would be if PHP *already* has integrated processing of JPG files, wich maybe true, judging by the intricate relation of PHP and internet, and JPG being this commom. I think a file extension wouldn't stand in the way (wich I think is what you, Phil, meant by "stored as binary" - no extension) Just check that. Also, Phil, snipets of the code you use, help you and us much better.
