After the 4.4 update on my Galaxy S4, totally unable to delete photos from DCIM directory. File size got huge. I tried solutions from many forums but no luck. Finally, I just got out my 2 year old Motorola, stuck the SD card in it and deleted the pics I didn't want.
Crappy fix but at least it works. Most of us have an older Android laying around. If not, borrow a buddy's phone.
