HI !!! I use gimp(1.2.0)-perl for making gif images in batches and a batch is of around 5000 images(gifs). What should be the ideal size of the tile cache(currently 50m) so that gimp does not create a swap file.(it takes up all the disk space in one batch) I delete the image after I save as gif so that only one image is open at any given time. secondly I dont want to store the undo information "gimp_image_disable_undo " gives me protocol error and the same error results if I set the undo-levels to 0 in gimprc Why ? what should I do ? somehow I have not been able to use the gimp-comment parasite I will be highly oblige if someone can please show me how to add a gif comment. programatically. Thanks in advance Chetan
