I have a relatively new blog, and up until recently I have been uploading full (or almost full) size images on my blog. Unwise, I know.
Obviously, my media allotment is getting eaten up quickly. I plan to upload reduced image files going forward, but I’m wondering if there is a way to easily scale down the photos I already have in the media library, or do I have to manually replace each photo in each post with a new, reduced upload? In that same vein, is there a way to insure that the URL is the same as the previous image URL (so that sites that have linked to my image don’t get messed up?)
