Iphone 6 won't let me delete photos

Question

I synced my iPhone with iTunes and all of the pictures from my iPhoto synced and now I've got full memory since all of my pictures make up about 6gb. How do I delete these pictures?

Hello michqnxx,
I understand you have synced your photos to iTunes and now want to delte them from your iPhone.   There are several ways to do this, and I'll include all of the information in this post.
If the photos on your iPhone were synced from iTunes to begin with, here's how you would delete them:
Sync photos to your iPhone, iPad, and iPod touch in iTunes - Apple Support

Delete synced photos
In iTunes, locate and click on your device.
Click Photos.
Choose "Selected albums" and deselect the albums or collections you want to delete.
To delete all synced photos, deselect "Sync Photos from" and, when asked, click "Remove photos."
Click Apply.
Learn how to delete photos and video synced from iTunes when you can't access the originals.
If the pictures were taken with the iPhone and reside in the Camera Roll:
My suggestion would be to import the photos to your computer, and create a second backup of the images.  When the import finishes, you will be prompted to delete the images from the phone.
Import photos and videos from your iPhone, iPad, or iPod touch to your Mac or Windows PC - Apple Support

You can also use the Photos app on your iPhone to select the images you want to delete and then tap the trash icon.

Delete a photo or video from Photos. Tap the Photos tab, tap the photo or video, tap , then tap Delete Photo or Delete Video. Deleted photos and videos are kept in the Recently Deleted album on iPhone, with a badge showing the remaining days until the item is permanently removed from iPhone. To delete the photo or video permanently before the days expire, tap the item, tap Delete, then tap Delete Photo or Delete Video. If you use iCloud Photo Library beta, deleted photos and videos are permanently removed from all iOS 8.1 devices that use iCloud Photo Library beta with the same Apple ID.
Recover a deleted photo or video. In the Recently Deleted album, tap the photo or video, tap Recover, then tap Recover Photo or Recover Video to move the item to the Camera Roll or, if you use iCloud Photo Library beta, the All Photos album. 
Hope that helps ...
