Why are my pictures taking up so much space on my iPhone

I have an iPhone 4S w/ 16 GB of storage. I only have MAYBE 200 pictures at the MAX and, yes, a few videos only a few minutes long, but for some reason it says I have 8.2 GB of memory used on pictures. I just went through all of my pictures, and I was thinking there had to be some app or SOMETHING using a lot of picture memory somehow. P

Please, can anyone give me a little help and tell me what could be causing this?

How to tell apple an idea I have?

I just had a really good idea for all of the handheld apple products such as iPad, iPod (touch, nano, etc… ), and iPad. I was thinking we could have something called "My Habitat".It would be sort of like a case, but not exactly. It would be more like a box of some sort that have a case built in it, and then a door like the iPad cases that can seal shut and open easily. You can also hang it on the wall, shelf, or anyplace you want and if it ever falls off (which would be rare) the case would be so strong the iPad/pod/phone will stay perfectly safe! Also, it will come with a stand for you to place your device either standing up, or sticking on the side of a table/desk/anything!

What would be cool about this is that the habitat will be customizable. You could just go to the apple store and buy a standard case, but you could order a case on the apple website for only about 5 dollars more. What will be customizable is:
1. Outside habitat color
2. Outside habitat sparkles (optional)
3. Inside habitat skin
4. White or Black device crib (case that holds the device safely)
5. You name on the inside door and the color (It would be like "JOHN'S" in blue like marker then iPad/iPhone/iPod Habitat)

What do you think of this idea? I really like it, and although I don't have any idea on how to make it come to life, I know apple does. I really don't care about how I won't be credited, I just want it to come to life: D! How can I tell apple though on the internet?

IPhone 4S problem with volume

IPhone 4S problem with volume?!
So I have had my phone since June and the volume will go up anytime! I was wondering if I go to an AT and T store, can they replace my phone or will they tell me they can't do anything for me? This is bugging me! It's been like this since i got it in June. Or will they let me pay the extra money to upgrade, to the other phone?

I don't use ear phones either. And it happens every time!

What's taking up photo space on my iPhone?

I just deleted all my photos and videos, and it still says my photos are taking up a huge chunk of space on my iPhone (4S, 16 GB). I'm thinking maybe album artwork? If so, how can I delete the album artwork? Thanks for the help!
