Why doesn't iPhoto open automatically upon SD card insertion? Inserting a SD card no longer opens iPhoto.  When I open iPhoto, it does not show the SD card in the left pane.  This program has done this without a problem until recently.  The preference under iPhoto is set to SD cards to open iPhoto.  I have also gone to Utilities/Photo Capture and ensured that iPhoto was selected in the lower left corner.  I am at wits ends because this should work automatically but is no longer doing so.  Any answers out there?
A common fix for these type of issues is to reformatting the card with the camera and try inserting it again. Make sure you copy the photos from the SD Card to your computer first.
