Cheryl, Sorry, I've been having trouble getting onto the site all week!! They make what we call tape runners, sold at hobby stores or the double stick tape (yellow box) is also acid free) The tape runners can be refilled and they work like the white out "runners". That is my first choice.
I only use photo corners for special profesional photos that are considered non reproducable. However, I find photo corners take to much time!

The photo runners will dispense little squares onto your photos and they also make a repositionable tape that will set hours after you have done your page, so if you put the picture on and then decide while working on the page you want to move it you can!

If you go to a scrapbooking store and ask the salespeople for the adhesives they can show you. Hope this helps. Just make sure whatever brand you purchase says acid free and preferably Lignin free.
