I started using Aperture a year ago. I never spent any time watching Lynda.com or anything else, I just thought I figured the darn thing out, as far as downloading images. I plug my phone or Canon into the computer and download images. At the same time they're downloaded, I have them backed up to a USB drive attached to said computer. Now I'm trying to export images and Aperture is telling me that some of the original files are unavailable. What gives? I can view all the damn pictures using Aperture. Why am I unable to export them? Seriously, what gives?
EDIT: I was attempting to send a selection of images to that God awful facebook. Two separate accounts. One account ended up with 46 out of 125 images. The second account ended up with only 33. This makes no sense to me.
