Digital Photos, Photo Storage, Free Prints, Photo Albums

I’ve followed the instructions from Yahoo for choosing which photo storage site I want, but I just get a message that Yahoo Photos is closing — I’m in a “loop” that never resolves my issue. I have read extensively through the help topics and forums at both Yahoo and Flickr, but I can’t find anything that helps. Any assistance would be appreciated.

For my photography class I have 24 photographs that I took with my digital camera. I have to have all of these photos converted to slides. Does anyone know where I can get this done? How much will it cost? What is a reasonable price for this?
I have never done this before and there are several small business printing places around where I live, but want to make sure I don’t get ripped off.
My photographs are going to college board to be judged and graded.
