How big can I blow this picture up?

I used a Nikon Coolpix L110 digital camera in macro mode.It's a 12.1 megapixel camera with 15x zoom. I was wondering how large I would be able to get a print of this photo with crisp resloution. What's the biggest print I could get?

Nikon Coolpix s3000 not turning on, battery problem?

Bought this camera in 2010, and it lasted just a few days before the flash stopped working. I didn't keep the receipt and just left it for about two years. A few months ago I finally decided to send it to Nikon and pay the charge to fix the flash. Got it back, charged it worked fine. Brought it with me on a trip but forgot the memory card so I didn't use it. After a month I've tried turning it on and it won't and when I plug it in to charge nothing happens. I have a feeling the battery might have died from lack of use, or could it be another issue?

Nikon coolpix P510 vs Canon sx50 HS?

I cannot decide between these two cameras as I''ve already skimmed through some reviews. But I
am personally leaning towards a Canon sx50 due to the reviews that I've read and since I already own a NIKON DSLR D80 I wanted to give Canon a shot since I fell in love with the image quality that my friend's canon dslr photos takes. I'm not planning to go for a dslr since I wanted something lightweight and easy to carry around rather than having to carry my D80 with me all the time and it's so heavy! Also I know I should not be comparing a dslr camera quality to these cameras because Dslrs do produce much more of a richer photos but I just wanted something light and that still takes great quality photos that's a close call from a DSLR, and a great battery life. I also wanted to stray away from a digital point and shoot camera as It's durability doesn't last at all that long for me like my Sony cybershot so I am looking for a good replacement.So far from reading some reviews I've learned that…

Canon SX50 HS

Pros
longer battery life, flipview of the screen (to do self portrait shots) and I think that is a plus!

downside:
12 megapixel? (or should that be good ?)

whereas

Nikon Coolpix P510:

Pros
has a higher megapixel of 16 ( Which I heard that the higher the megapixel is the bad it is, is this true? how so ?) Much cheaper than sx50 HS! Great picture quality! (from what I've seen on instagram).

Cons
Read a review that the video on a Nikon coolpix P510 is bad and that there are times that it won't focus.

Note: I am not a professional photographer, just an amateur one !

How good is the Nikon Coolpix s3200?

I love taking pictures and I usually do it with my JVC video camera and I have come out with some pretty good pictures. I lost the charger for it a while back and I can't seem to find any online or in stores so I thought I might get a camera and I saw the Nikon Coolpix s3200.

I've heard mixed reviews that it takes great photos and ive heard it takes bad photos. I don't know how a lot of camera settings work so I look forward to learning it all but I want to hear from someone who has one and there personal opinion.
