Hello! I'm trying to make a picture frame out of old windows (see attached) but I cannot figure out how to affix the photos from behind the glass. I've tried spray adhesive on the corners of the photos, but it ruined the ink and didn't even stay for 10 minutes. Then I tried "invisible" tape, which was very much visible and looked like shit. The only other thing I can think of would be to use white washi tape and make it look like a border, but I really would prefer not to. Any ideas? Has anyone ever successfully done this outside of Pinterest?
