DH complains about the number of photo's i have on display (in general, not just of DD). I also have several albums but no rhyme or reason to them (must get around to sorting all that out eventually!). DD has one album just for herself which is already full.
I was chatting with an ex-BBer just after Christmas and she puts her pics in a digital photo frame - saves on printing and displays all your pics! The size of the memory determines how many pics you can display and they "rotate" your photo's. Eg, it will display a pic for a set time (maybe a minute) and then change the photo. I am keen to get one for DD's photo's but am yet to find a frame I like... and they can be a bit expensive...
