Why can't I download pictures I see on my camera roll into iPhoto or Aperture?

Incorrect. No apps on my Mac can see most of the photos in my camera roll. Not iPhoto. Not Aperture. Not image Capture. They all see the same one photo out of ten.

This is not an iPhoto problem. It happens regardless of which app I use. I'm not saying I can't download any photos from my iPhone. I'm saying I can only download one out of the ten currently in the camera roll. Yes, I can see my iPhone regardless of which app I'm using on my Mac.

For the record, I'm not using iPhoto. I moved on to Aperture 3 months ago.

I cleared the cache as your tip suggested. Whoooo... the next sync took ages as re-synced all of my images from my Mac to my iPhone. However, I still can't access 9 of the 10 photos in my iPhone camera roll when I try to import. Every Mac app gives the same result (iPhoto / Aperture 3, Image Capture).

Again, just to be clear, my Mac does see my iPhone. But I can only import one of the photos on my camera roll.

I've come to realize that the problem is most likely a corrupted image file on my iPhone. If I delete all images from my camera roll, the camera roll shows as being empty, but on my Mac, I see one image. The image only shows as an outline, and importing it gives me an error. Let's say I take five pictures. I'll see five pictures in my camera roll, but if I try to import them, I still only see one image and it shows up as an outline but can't be viewed or imported.

This leads me to believe there's a corrupted image on my iPhone, and that any photos taken after it won't be viewable or importable.

So... the question becomes: how do I delete the corrupted image? Or ALL images. Either way is fine.

If I go into the camera roll and delete images individually, I can only delete the ones that are shown. Again, assuming I take 5 pics, I'll see 5 pics in the camera roll. I can delete those 5, but there must be one more earlier pic that is corrupted.

That's my best guess. Now, I'm trying to figure out how to delete an image I can't see. Bizarre.

"just go into your iphone from finder and drag the photos out and then you can just put them in iphoto from there"

How do you do that? I tried using iPhone Explorer, but I can't find where the image would be.

I've tried looking in the finder. I didn't eve realize you could see an iPhone as a usb drive in the finder. I don't see mine (but maybe that's because of the corrupted file?).

If I restore my iPhone, am I going to lose my data? I realize there's a backup on my Mac, but wouldn't a backup also include the corrupted file?

The corrupted file was a photo edited last week. That much I do know. I could see it in the camera roll. I deleted it that way, but I'm assuming it didn't actually delete.
