It is not possible to just "convert" bitmap images (for example .bmp) and make a document from it (like generic .doc). But, you may import the picture as object on one of the pages in the document. This is usually done through some "import picture" menu option in a word processing program.

The table with program actions contains information about what each program is capable of doing with their files. This may be a good pointer for further searches for certain file conversions and help you find the converter you are looking for if our search result is insufficient for you. However, it is far from perfect and may sometimes show results which are not really usable because of the nature of the software handles the files. So a conversion that appears as possible, just because of matched actions, may in fact not be possible.
