Image Transform 1.3
Image Transform can open images in the GIF, JPEG or PNG formats and perform operations like resizing, cropping, rotating, flip or grayscale convert. The original proportions are kept when resizing images.
The transformed images can be stored in server side cache files to avoid overhead of serving images processed with the same operations. Processed images are served as the output of the current script.
