Hi, here is my method for converting a folder full of jpg's to a specified thumnail size.
some requirements that can be changed in the code are;
folder structure should follow;
-main folder
|-code files
|-"images" folder
|-"thumbs" folder
the file naming convention under the images folder should be
-"images" folder
|-001.JPG
|-002.JPG
|-003.JPG
|-so on up to 999.JPG
here is the code I use to create the thumbs into the "thumbs folder"
note: to display the images youll need to write your own customized code.
Whats good about this is just upload the pics to the images folder, run the
code in the parent folder and all the thumbs will be created automatically in the thumbs folder...
hope this helps someone... and im sure it can be optimized...

// Beyond this point is simply code.
