41 double-sided pages included.
Originally you just laid a picture on a page anywhere you liked, laid the plastic film over it and any other pictures on that page, and you were done.  But now in case the sticky-note abilities of any page is weakened or even gone altogether, You could put pictures 
in it a number of ways.  Here are some examples:
  • Use traditional "corners"
  • Use a dry stick to apply double sided tape in one or more small places on the back of your picture
  • Wrap a piece of clear adhesive tape (however long  you like) in a circle with one end attached to the other and the sticky side out,  then lay that on the page and the picture on top of it.
Let the clear plastic sheet back down over it all.
