I have some codabar barcodes, saved as png files.
The filename is the number in the code.

I want to put them together in an image using a script, to be printed out. The number (filename) must be centered under the code in about size 13 Arial. This image must be the right size to print on 8.5x11 paper.

I thought about using PHP or The GIMP. But PHP isn't very good when it comes to placement of TTF and I know almost nothing about Python or GIMP scripting.

Any suggestions of what to use? So long as I can make a page in < 30sec it would be fine, doesn't need to be a script.
