Just open up a pic in photoshop and then click save as... change the name to something like pic1lowres instead of just say pic1. That way you will be able to keep the hi res version for yourself or email. But then click save once you have changed it and a promt for picture quality should pop up, when it does drop the quality down to around 2 or 3 and then click ok. Then go to the photo album and in the browser just search for the file you want and fill in all the fields and click submit. Then when somebody authorizes your pic(s) then they will be up for the world to see.
