> When you say "resize" does this include reducing the filesize or is it merely reducing dimesion?
both. Imagemagick is a collection of programs, the one i use the most is convert.
it can convert from say gif to jpg, change the size ( in dimentions ) and you can set a quality setting if the output is jpeg.
When I'm talking about quality, i'm not talking about jpg "quality" but the quality of the resize (resampling) algorithum. I have seen sites that use GD and their thumbnails are all rough and low quality, wheres covert resizes an image as photoshop does, buy resampling useing complicated algos.
>Is there a gui for using im on the server like a graphics program?
it's a UNIX program, that will run on unix servers. There is a gui for it, but i'm not sure how you're supposed to control a GUI from a php script ;)
ok i found a site that compates the quality between GD and netPBM ( although not imagemagick, imagemagick is as good as if not better than netPBM )
