Hi! all. need help to reduce file size of jpeg pix taken with my Nikon DSLR. cause my friends want me to email to them for them to post on the web. Would be good if theres a program that can batch convert the file size of the jpeg files to a smaller size for both printing & publishing online. I currently have Photoshop CS4 but not sure if it has the function. if there is can anyone provide instructions on how to use it to batch convert? Appreciate everyone's help.
