Convert Images to Thumbnail Images
This image convertor uses features to automatically change a normal image to a smaller thumbnailed version of that image. To get started make a main folder for the thumbnailer to work. Now in that folder make two sub folders: main and thumb. Make sure to chmod the main and thumb folder as chmod 777.
Now, in the main folder throw in some of your normal large images, copy and paste the code below and place in you root folder that contains the main and thumb folders, and call the file index.php. Launch the index.php file, and it will begin to remake your large images to small images, and place them into the thumb folder.
