Places like Staples will not print your images on cardstock because they are Disney - they don't want to violate copyrights and trademarks. Places like
Walmart, Walgreens, Shutterfly, etc. will print them as photos. You can also upload them and make them into a photobook.
If you use Sharpie markers they will not smear, even on the glossy photos. I recommend the retractable ones so that you don't have to mess with taking off and putting on the caps. They can bind the photos just like they were pieces of cardstock, but you will lose the top 1/2" of the image. If you don't want to do that, you can slip them into a small photo album to carry them around the parks. Come on over to the Autograph Thread for more ideas and answers.
