I need help!!!! I put my photos in my scanner and when they come up I have to crop them to make them full screen. When I run them with slideshow they come up grainy and I get an X telling me they are not the right target display size of the slideshow album. it says I need to make the necessary adjustments but I cant find out how. Please someone help me with this. Im trying to do a slideshow for our church. Thanks so much. You can email me at peachy67@insightbb.com Thanks!!!!!!
