Image format

[NotAGolf]

I've got a couple of hundred images that I need to convert from a .png format to a .ppm format. I've had a look but I cant find any converters that are any good, they either dont work, or have silly limitations like maximum file size or only can do one file at a time. At the minute I've done it by opening the .png ing photoshop and then saving it as a .ppm but as you can imagine this is pretty time consuming. Anyone know of any decent converters or ways to speed up my current method?

Also, it has to be .ppm not .pbm / .pgm.

Thanks for any advice.

Thanks whitecrook. I made the .bat file and dragged the folder onto it. It made the c:/out folder but it is empty. What does that .bat file do? I have never seen code like that before.

Thanks again.

No worries, I made a quick Java file to generate the individual calls then put them all in a bat file so it's all done now. But thanks for the advice anyway.

Just for my info really but does that language have a name you used whitecrook or is it just common windows language?
