A 5 MP camera will make files about 3-3.5 MB in size for an "average" full size, maximum resolution picture. Sometimes more and sometimes less. If you use smaller pictures or more compression (less detail), they can be quite a bit smaller, like down to 1-1.5 MB. Count on 3 MB for guesstimations and you'll be safe.

5.1 mp refers to a 5.1 mega pixel camera
so there are 5.1 million pixels in one photo. The question is in how much memory you have on the camera and the actually quality. If you put a 1 gigabyte memory card in usually it takes only 0.10% so you can have about 1000 pics or 1 megabyte per picture.

Depends on whether you are shooting RAW or JPEG, and the degree of compression.
The table below shows how, on average, a five megapixel image (2,560 x 1,920 pixels) is compressed using the various image formats which are discussed in this glossary. Please note that in reality, the compressed file sizes will vary significantly with the amount of detail in the image. For example, the table shows 1.3 MB as file size for an 80% Quality JPEG five megapixel image. However, if the image has a lot of uniform surfaces (e.g. blue skies), it could be only 0.8 MB at 80% JPEG quality, and if it has a lot of fine detail, it could be 1.7 MB. The purpose of this table is to give a ballpark estimate.
Image Format Typical File Size in MB Comment
Uncompressed TIFF 14.1 3 channels of 8 bits
Uncompressed 12-bit RAW 7.7 1 channel of 12 bits
Compressed TIFF 6.0 Lossless compression
Compressed 12-bit RAW 4.3 Nearly lossless compressed
100% Quality JPEG 2.3 80% Quality JPEG 1.3 Sufficient quality for 4" x 6" prints
60% Quality JPEG 0.7 Sufficient quality for websites *
20% Quality JPEG 0.2 Very low image quality

The simple answer is: It depends!
It depends on the settings on the camera, specifically for quality and compression. With no compression you will use roughly 5Megs.
Similarly, it depends on the picture. With compression turned on it is possible to group areas of identical pixils into just a few bytes so you could compress your 5MP file into only 1MB.
It all depends.

i don't even think that picture will count on your mps.
i have a 4 mp, and it doesn't even show that it has taken any space
on my memory card
