Things You'll Need
Instructions
Test each corner of the photo with your fingernail to find the loosest corner. You can also use a thin metal spatula or butter knife to do this step.
Pull the corner back just enough to be able to slide a piece of wax-free floss underneath it. If you do not have wax-free floss, use a piece of thread -- although you may need to double it up for strength and a better grip.
Work the floss across the underside of the picture, carefully separating the photo from the album page. Move the floss in a diagonal direction, and slowly move it back and forth under the picture.
Start on another corner if you meet any resistance -- don't force the floss, or you may end up ripping the picture.
