Hello. I am wondering when you sell digital photo files to clients for web use only what compression do you use? Would a resolution of 72 and a medium compresses jpeg be small enough to prevent theft of web but still look okay on website? Also if my image file at 100 percent is 15x10 what size should I crop it down too if at all. My goal here is to provide the clients with a file that will work nicely on their site, but prevent them from being able to print that image if they did not purchase the licensing rights to do so. Thanks!
