Script to generate gif from folder of images

Question

Not super familar with scripting, how would one create a script that you could point towards a folder, and it would itterate through each subfolder, turning it's contents into a gif with the name of the subfolder? The images themselves in each subfolder are ordered, so there would be no major concern of it getting frames wrong.

Thanks!

@111aaa11 – Here is a new version to automatically process all sub-folders under the selected top-level folder.

EDIT: Original code updated to 1.1 to correct an oversight where %20 characters were output instead of word spaces in saved filenames.

@111aaa11 – I believe that I have found workable Windows code for the recursive folder/file selection. I don't know why the code I was using only works on the Mac.

Before I incorporate the folder/file processing code, please confirm that the following script works as intended. This code is only for selecting one sub-folder at a time under the root/parent folder.

If this works as required, I can add the code to process all top-level sub-folders under a selected root folder.

EDIT: Original code updated to 1.1 to correct an oversight where %20 characters were output instead of word spaces in saved filenames.
