I did have a few questions though. I used E6000 glue to paste the pictures as well. Someone suggested clear nailpolish for the pics but when i tried that, the nailpolish dried so quickly that it did not help to stick the pic. so I decided to use e6000 for pics as well as the magnets
However, this glue is not very easy to work with in that, it's not snooth and spreadable. Anyone can suggest a more spredable glue for the pics. E 6000 was fine for the magnets..dries very fast.
i use e6000 every time. one very easy way to do this is to NOT cut your pictures out first. instead, just print them out into about 3 inch squares, then dab the glue directly from the tube onto the marble, and then press onto the picture, allowing the glue to spread out and cover the entire picture. when it is completely dry (about 1 hour give or take) use a small scissors to cut the marble off the paper--just cut around the edge of the marble as close as you can. then glue the magnet to the back and voila! you have a perfect magnet every time. (i use curved cuticle scissors to cut the marble off the paper--easy to move around the little marble!)
