i look after a website that has a photo gallery. the society that the website is for has now changed and as such i have decided to take this opportunity to recode parts of the website to work better and resize some of the images to take up less space
The website is on a linux based webserver, what i would like to do, and have no idea if it is possible would be to resize some of the images through the use of a script. is there a command line based tool in linux that is capable of doing this?
I know there are some PHP libraries that are capable of resizing images on the fly, but i want them permanently that size - is php the way to go.
(if poss i would also like to watermark the images too)
