How do you move pictures from iphoto to a memory card?

The simplest way to do this is to go to your iPhoto library, right-click on the photo you want to put on your memory stick and select show file. This will bring up the picture file in a finder window. From there you can copy and paste it to your memory stick. Another way, which works better for multiple photos, is to select any pictures you want to put on your memory stick, go to the File menue at the top of the screen and select export (this can also be done by selecting the photos and pressing Command, shift, and E simultaneously.) A box will come up and you can select the names, sizes, and types of the picture files you are exporting. Click export and select your flashdrive from the left of the finder window that comes up. Select OK and your photos will be exported to your memory stick from your iPhoto library.
