I understand things about pixels, but if you take two cameras, say both 5 megapixel and look at the photos on your comp, one can be significantly better quality than the other, why??

Edwin - thanx but what's ISO ?

As mentioned, the quality of the optics (lens) is a large determinant of image quality. I've never understood people paying a premium price for a camera and then buying cheap lenses. Its sorta like putting used tires on your new car.
Its also possible that different ISO settings were used. If one 5mp camera was set at ISO 100 and the other at ISO 800 you'd definitely see a difference.
EDIT EDIT EDIT EDIT :)
ISO is a measurement of the sensitivity to light of a light-sensitive surface, either film or digital sensor. The higher the ISO the more sensitive. There is a trade-off, however - at higher ISO's you lose image quality.

Sharpness, not from pixels, but from focus, is very important. Make sure the most important part of the photo is in focus, and the unimportant parts are a blur from motion or wide aperture.
Composition is also important. Placing your main subject off-center makes for a more interesting composition. Horizons placed high or low are more interesting than center. Level is good, unless you are deliberately going for an angle to increase tension. Having something like a path to lead the eye into a photo also helps.
The difference between two cameras is probably in the lens, if it's the same person using the two. A better lens can make a big difference.

pixel size as well as count, bigger cameras such as dslrs have bigger sensors so between a compact with X resolution and an SLR with X resolution the SLR will give you a better picture (assuming all other factors are equal)
bigger sensors also mean you can be more selective with focus and depth of field control, adding to the look of the image.
the recording mode can also affect quality, if you save at RAW or TIFF you are likely to end up with a 16bit depth colour image (millions of shades per primary colour) if you take them in JPEG mode then you'll end up with an 8 bit colour image (256 shades per primary colour)
An SLR is likely to have a better lens, or at least the option of fitting a better lens.
Then there is the ability factor, knowing what settings to use & when, how to compose an image etc.

Shutter speed, lens quality, lighting....
Also, the cameras may both be 5 megapixel, but are the pictures they took 5 megapixel? You can set the resolution to a lower setting on most digital cameras.

A co.mputer monitor can't begin to display the resolution today's cameras are capable of. One camera might have a superior lens, another might have better performance at high ISO settings, another might have better noise reduction, so yes, you could see a difference, but not necessarily because of the number of pixels

The steadiness of the shot contributes greatly to the quality of the photo. Using a tripod for wedding or portrait pictures are the norm. by many professional photographers and they don't do this for any other reason than to improve the quality.

quality is the lighting used, the exposure, the view point and composition etc - skill of the fotog not the tool used
the image enters the camera via the lens, so a quality lens makes the biggest difference to me,
i shall explain it like this --- 5mp camera with a crap lens will give 5mp of crap, 5mp and a sharp lens will give 5mp of sharpness

generally its to do with the person pressing the shutter...
theres more to taking pictures than just pressing the button...
i know, i teach photography...
one 5mp image is like any other 5mp image... i could show you images from a 3grand hassleblad and a 30 quid lubitol... and you couldnt tell them apart, until i showed you what to look for, and at...
however. a 5mp nikon image will look better than a 5mp nippon no name... its to do with the lenses and the metering system... if we could get away with a 30 quid nippon rip off, instead of a £3000 nikon we would... but for your 3k you get a lot more than just a name on a box.. and it wont break.

The most important thing is the quality of the lens
