Creating an image from 9 images, in a 3x3 fashion
<p>Here's the idea:<br>
I have a folder with 9 images in it. The 9 images are like pieces of a puzzle (except they are placed in a specific order) and the output should be something like this (numbers 0-8 represent the images) stored in a new .jpg file.</p>

<p>0 1 2<br>
3 4 5<br>
6 7 8</p>

<p>I've searched a lot, and I've found how I could make them all line up, but I haven't found a way to arrange them in this matrix-like fashion.<br>
Any help?</p>
