If you use a tab roller, instead of rolling on the tabs, use it as a dispenser and put the tabs only where it's needed. (i.e., one on each corner and along the edge of a photo...)

If you need one-sided adhesive, (to tape down fibers to the back of something you just wrapped it around, for example), use the leftover bordering material from a sheet of stickers. You know, what's left over from around the sticker after it's taken off the sheet? Just cut or tear off the size piece you need. Voila! Free tape! And you already know it's photo-safe.
