How to delete photos for good...

Question

Apple has to have the worst phone I've ever had the misfortune to use not because of the phone, the phone itself is a pretty solid device but because of apple lacking any sort of ingenuity or technical finesse in their software design other then turning everything into a marketing kiosk
First time having and iphone and will be the last time
Down to brass tax, before i start some god awful rant about craptunes
Essentially i'm trying to add more music to my phone but i don't have enough space, WHY? because apparently the phone has withheld 1100 photos from existence. See when i use the photo browser on my phone we all know how we cant just look at a feed of our photos anymore instead the dullards at apple decided you can only have a 350 cap on most recent shots and its impossible to view any previous shots without delving into the god awful time consuming collections feature. There's about 5 maybe 600 photos on my phone, i'm not a big picture taker but iTunes says there's about 1100 at 1.75gb how can this be?
I can't even see all the photos on my phone let alone see them if i tried to back my phone up...
Even looking at my photos in collection i can confirm there isn't even that many there, I've had the phone for half a year for pete sake
I can't get over how unintelligent a multi-billion dollar company can be, my apologies but bear with me my non-apple associates!
So what do i do? I know i could clear up more space by delete photos i don't need but i cant even see them, **** i cant even back up photos in a clean jpeg format without plundering a handful of oddly named folders on the windows file explorer and even then i wouldn't have my space back.
How do i delete or even access this hidden cache of said "Phantom" photos
and on a side note why the **** is "other" so large about 2gb for me as well as documents and data yet again another mass of files i have zero control over growing in size daily
Thanks a ****'** lot crapple.
Any help from the community is greatly appreciated.
And if you're an apple fanboy please withhold your flaming my opinion is my own and it was largely influenced by the crap software apple offers. 

Answer 1

When you double click on of the these blank thumbnails to view the photo in a larger size do you?
First make a temporary, duplicate copy of the library and try the two fixes below in order as needed:
Fix #1
1 - delete  the iPhoto preference file, com.apple.iPhoto.plist, that resides in your Home/Library/Preferences folder. 
2 - delete iPhoto's cache files that are located in your Home/Library/Caches/com.apple.iPhoto folder. 
3 - reboot, launch iPhoto and try again.
NOTE: If you're moved your library from its default location in your Home/Pictures folder you will have to point iPhoto to its new location when you next open iPhoto by holding the the Option key.  You'll also have to reset the iPhoto's various preferences.
Fix #2
Launch iPhoto with the Command+Option keys depressed and follow the instructions to rebuild the library.
Select the options identified in the screenshot and the option to rebuild the small thumbnails.
Click to view full size
Then see if you can drag the  thumbnails to iPhoto's trash and remove them permanently.
