Photos disappeared
I downloaded my photos from my camera SD card to iPhoto and viewed them. Then I downloaded about 20 more from my iPhone. Now I cannot find the photos I had originally downloaded from the SD card. Where are they?
Which version of iPhoto do you have?
You should be seeing all photos, if you click the Photos view in the sidebar. Scroll through your photos, if you can see the missing photos. Or are there broken thumbnails with an exclamation point?
