I have a 4th generation Ipod touch. After downloading pictures to my Ipod Touch straight from my SD cardreader the downloaded picture format changed on my SD card. I can no longer display my pictures on other mediums (i.e. Snapfish, Facebook) from that SD card. For pictures taken since this happened I saved them to a folder on my Macbook before trying to put them on my Ipod touch. I get an error message saying that my Ipod is synched to another photo folder and did I want to replace the existing photos on my Ipod with the ones in the new folder. Can't I switch places from where I get pictures without getting an error message? Seems pretty silly that I can't. Thank you!
