Why do I have 2 of every picture side-by-side in my Photo Library? I don't edit or rename pictures at all. All I do is take pictures. Then sync phone to my Mac with iTunes. But Photo Library on iPhone shows 2 of everything without a trash can to remove them. What is going on?
Chances are, you are importing these pictures into iPhoto. After that, under the photos tab, when you have your iPhone plugged in, is a checkbox to sync photos from iPhoto. This likely is checked. If these two things are correct, it will then transfer back onto your device, all the pictures that were/are on your phone. This is the only time I have seen pictures that I can't delete (that don't have the "trash can").
If this is the problem, it could be easily remedied by simply disabling the sync checkbox under the Photos tab for your device.
@bassplayer7 is correct, and here's the breakdown.
Steps to recreate the issue:
Presto! Two sets of the same photo(s).
Reason there is no trash can:
The confusing part about it, is that when you look at the iPhone 'Photo Library', they all appear combined. The distiction you can see is that the 'Camera Roll' should only have the copy you took on the device, and there should be a folder in the Albums list that shows the items imported back from iPhoto.
The solution: Check your settings on iTunes and iPhoto. Decide if you want iTunes to copy the last import back to the phone, and on iPhoto, check if you want to import and delete.
Hope that helps!
I'm not sure what you mean about the "trash can" (could you post a screenshot?) but if you have the HDR option turned on in the Camera app, it will create two copies of every photo - the standard camera capture, and a copy processed with HDR.
You can toggle HDR on or off before you take a photo by tapping the Options button that appears over top of the screen when running the Camera app. There is also an option under Settings -> Photos (Keep Normal Photo under the HDR section) that, if turned off, will only keep the HDR version of a photo.
