I did exactly as Roger noted - optimized the files in my computer, uploaded them to photobucket, then copied the new location information and replaced it in my post. I'll then delete the old high res photos from my bucket. I'll use it on future posts, but won't bother to replace any more of my pics. At least I know that I won't use up my free space while posting on my current build log. It's got to be more than half way done.
