Generating x number of pictures

I need to generate pictures with a certain size (in pixels). Each picture will have an incrementing number in it. That is all that will be in the picture, a number. I'v开发者_运维问答e been thinking of using photoshop but I have no idea how the scripting works. Any suggestions or examples I could use?

Try using ImageMagick (http://www.imagemagick.org) and its text handling feautures (http://www.imagemagick.org/Usage/text/).

#!/bin/bash

   echo Generating $i...
   convert -size 256x256 xc:black \

done

And the result:
