I am trying a crop method and was wondering if it is possible to crop in the center/middle of a larger image instead of from the specific pixel measurement from the top left. Regards Jan

For example... use the readImage() method to return an image object, then the getImageInfo() method to get its dimensions. startx = int((originalWidth - desiredWidth) / 2); starty = int((originalHeight - desiredHeight) / 2); THEN call the crop image with those dimensions and pass in the image object instead of the file path. Although it takes a few more lines of code, it shouldn't perform any slower since there's still only one file read and and one file write.. the rest of the stuff happens on the image object in memory Rick Rick Root I'm not certified, but I have been told that I'm certifiable! www
