Removing photos from phone

Photos app select photo then the trash can icon.

I have to be missing something? Is that what you meant?

 

in an album press select, select photos to delete then press the trash can. isn't rocket science.

 

Sync the phone and uncheck the sync box on the photos tab. It will remove all of them. Be sure to save them somewhere first if you don't want to lose them all together.

 

Ok so from what I gather you already have the required backup for the photos ... best bet right now would be to DELETE ALL from camera roll then use iPhoto to create Events/Albums and sync them back via Photo option in iTunes

Now to delete all from Camera Roll is a bit tricky as iOS doesnt allow it..

What you can do is use iPhoto or Image Capture app on a Mac to IMPORT all photos from the Camera Roll ... and after import, the app prompts you if you want to remove all the imported ones from the phone ... just select Yes and you are done (You can of course remove these imported ones from the app)

 

If you do Import All and then do the delete option later it should empty out the Camera Roll

 

Image Capture

+1 for Image Capture.

As you mentioned iPhoto I presume you have a Mac.
If you connect your phone to the Mac and launch 'Image Capture', you can select as many photos as you like at once and delete them.
