Saving picture on Nikon Coolpix S6100?

I got a new camera and I had an amazing picture of a sunrise on it that I set as the welcome screen. Well I was playing around and was deleting pictures and accidentally deleted it. I can't pull it up to look at it but it still is my welcome screen. Anyone know how to get it off or resave it.

If you have the money. (Nikon D5100 or D7000)?

Would you get a Nikon 5100 with kit lens, or 7000 with kit lens?(And its your first SLR)

Personally,I know quite some basic stuff on how to balance between the shutter speed, ISO, and depth of field since I have used my parents old canon powershot S2 which also have those 3 for practice(shutter speed, ISO, and depth of field).

I don't mind reading manual book, but then again, what is the in camera guide? I'm currently somewhere technology are very expensive and we are not allowed to touch them, unless we buy them.so I haven't hold any of those two DSLR, other than review.
(I'm buying it in another country probably next year January)

Although people say that a beginner better start step by step(taking D5100),I like the less noise in low light condition of D7000 and its Quality Build. If I buy D5100 first and buy some more lens, if I need to upgrade, it will take way too long for me to save those amount of money. I even sold some of my stuff to get that budget.

So, if you were me, which one would you choose? Sorry for long detail. Thank you

Trouble with my nikon coolpix p510?

So, i recently purchased a nikon coolpix p510 to dabble around with. Dont know much about cameras. About a year ago a friend of mine showed me this light trick when its night and they hold down the shutter for 30 seconds or something and you can draw and see how it turns out right? Well, all i know is like i think that's how long the shutter is open and when it closes, it will show the picture put together right? Something like that? Can anyone explain simply how it works and how i can do it on my nikon coolpix p510 camera?
Added (1). So, i went to the "S" setting which is "shutter priority auto and i went to menu and clicked on "continuous" and theres a section where you can change the Intvl timer shooting to 30 sec 1 min 5 min or 10 min and i also found a dial i can turn which changes something like 1/4000 and lower, does that mean anything?

Nikon Coolpix P500 shutter speed/aperture problems?

Ok, so recently i got a nice Nikon Coolpix P500 camera for my birthday :) i love it so much! everything is perfect about it… except one part. For some reason, when i try to use my shutter speed or aperture settings it comes out either completely black or extremely desaturated! I want to be able to capture fast shots of my dog and little brothers but the only way Im able to is if i want a dark, nearly colorless photo. I have even read the manual which gives no information. I searched the correct settings that are compatible with one another but it still comes out terribly. The only thing i can think of is the ISO setting but I've tried all that the camera offers and it hasn't made a difference.
Added (1). Oh, and i have tried using these settings inside, outside, in bright light, in low light.and still they come out either completely black or very dark/colorless and have gone over the manual many times.
Added (2). The auto setting does NOTHING for what i want
Added (3). I dont know how many times i have said this. Ive taken photography and am in an advanced art class where photography is my focus.Im not an idiot, i know how light effects the settings. What im saying is that no matter what i do on the shutter speed or aperature or manual settings, the pictures come out dark or nearly black and white.
