I’d be tempted to mount them in larger frames with chunky white mat board to lighten up the feel - depending on where you want to hang them i’d prob break up the collection -

Here are some options.

25 pictures is a lot to look at. Consider displaying 3 - 5 at a time re-framed and matted as suggested. The remaining photos can be arranged in a acid-free scrapbook that can be on a coffee table or shelf in your new home so you and others can sit down and look, enjoying the changes over the years.

Or, save the 25 years on your computer and have a photo book created by the companies that specialized in that. Archive the photos, leaving 3 - 5 on the wall.
