.....Any script you find here is probably intended to be run on the Kindle.
Forgive me, but this is the part I do not understand. Installing the jailbreak and hacks stretched the limits of my ability. I assume this must involve the usbnetwork program or some other terminal program, but it seems dangerous for someone who doesn't know exactly what they are doing to try this. The readme file for the USBnetwork file certainly says that.
..... Why in the world .... ? Write a script file that runs on the Kindle.
It can probably be done as a single line command.
Well I have a few hundred images (I know I can only use a 100 at a time). So I thought it would be easiest to make the conversion on my PC. Especially since I do not understand how to send the command to the kindle.
....Since you give zip, zero, nada amount of information about your programming background, I can't know what to write that might help you.
I have written very basic batch programs in the past. That is it. I downloaded the imagemagick program and it seems for someone with a bit more knowledge could write a batch program to run the same adjustments as in the script referenced in the linked post above.
I know I can figure out the DOS batch stuff eventually, just thought someone could do it much quicker.
