I Need Ideas!!

I am asking for help on a few things here.
I am trying to redo my walls in my house, by that I mean I am trying to find neat, cool, inexpensive ways to hang my photos, and all of my children's paintings that they have done in painting classes. I found a few ideas but I am looking for more. So if anyone has any let me know please.
Next I am thinking of repainting my bathroom (I know honey just leave it alone, and I will not do it.) but I need to find paints with no Oder, that work well, and are save for mother earth. If anyone has used any of these types of paint, and know if they work well or not, please let me know.
