In the days before StackExchange used i.stack.imgur.com for images, I had linked quite a few images to my college's web server. Now all those links are broken, and I will eventually move them to i.stack.imgur.com. But the consequence is: the old posts get bumped to the frontpage. To turn this post into a question:
Q. Is there a way to edit a post without bumping it to the frontpage?

I believe I have now updated all the lost images and broken links in my postings (triggered by an email/username change from orourke to jorourke)—approximately 200 postings. I appreciate everyone's tolerance during this six-month process. Thanks especially to @MartinSleziak for retagging.
