Your question is confusing. You ask to maintain the original image size, but go on to say the standard image size is no good. Are you referring to aspect ratio? If so, there are two ways to go about it:
One is going to be checking the DPI (dots per inch). An image will usually default to 72 DPI but the printer will default to 300 DPI (examples), which means your image will appear 3x smaller than it really is. Have a play with those settings.
Then, create a table in your word processing application and simply insert the image in there. You can then adjust the scale to your liking and put as many versions on the same page as you'd like.
