A few tips:
Just pick the drop down you think fits best. If you're not using a stampin up stamp, then choose a technique or something under "anything but a card". If you're really not sure leave it in your member gallery.
Before you upload your image, change the file name to something unique. What I like to do is add the date to the end. for example momsbdaycard092109.jpg
