The BIG house

I took Madders and Collin to the Casa Grande Ruins for a project I had to do for my AZ Government class. They had lots of fun, learned about the Indians, and were able to earn their Junior Ranger Badges. I would put a caption under each picture but well, blah. I already created a 28 page powerpoint presentation for it and don't want to do it again. Wish I could just upload the power point to the blog. Anyone know how to do that?
