Multiple images into ONE large image using PHP?

[galvin]

If a user uploads, say, NINE jpeg images to my server, can I use PHP to then create ONE large jpeg image that contains all nine of those images? 

 

In other words, say each individually uploaded file was 100 x 100 pixels.  I would want to create ONE larger image that is 300 pixels wide by 300 pixels high and combines all nine smaller images (in a 3 by 3 grid essentially).

Picture a Tic-Tac-Toe board as being the final single large Image with each individual smaller image being in one of the sections of the Tic-Tac-Toe board.

 

Is this process of combining multiple images into ONE image possible with PHP?

Yes, look at image gd functions

Ok, thanks.  I don't see anything about MULTIPLE images though. Can you give me any insight on how to create an image from MULTIPLE images.  I imagine I would have to use the function imagecreatefromjpeg() but is it OK to put more than one souurce file as a parameter?

There is no pre-built function for it, you need to learn how to use image GD functions.

 

You could always use CSS/HTML to just visibly merge the images on the page.

if you google php watermarking, you should find what you need.  It's mostly the same principle.

use a for or while loop and imagecopymerge to combine them all
