1) why is it important?
Different image types (bmp, gif, jpg, png, etc.) have different space requirements and different levels of quality. Bitmaps take up significantly more storage space (and are therefore slower to load on a modem) than most other formats. So, you want to convert to other types in order to save space and loading time.
2) how do you do it?
Open up any generic image editing program. Even Paint will do. Open up the .bmp image in that program, and then go to "file" and "save as". On your save-as screen, there should be a "save-as type" drop-down menu. Select whatever type you want there.

IIRC, only versions of paint from XP and later gave you that option.
nab irfanview it'll get the job done.

Wow! what an awesome program....many thanks!fliptw wrote:IIRC, only versions of paint from XP and later gave you that option.

and BTW, what does "IIRC" mean
will_kill,
there's a little more to it.
There are ways to reduce the size of a file, particularly of image files. Some compression methods are lossless, i.e. all information of the original file is still somehow available in the compressed file. An example is PNG, or some TGA sub formats.
Other compression methods loose some information. These formats usually work with the weaknesses of the eye and try to trick it so that the compressed image looks very much like the original. The higher the compression, the lower the image fidelity. A good example is highly compressed jpg: You will notice the quality loss in the image.
So if you want to send images somewhere, chose a compressed file format. If 100% fidelity to the original is not required, you can e.g. chose jpg.
