I do this with several sites. I usually have a field in a table for the image file name (image1.jpg, for example). Then I make sure all of the images are in a specific folder (ImageFolder, for example). Then in my cfquery, I have it select the image name from the table, and I have it output into a html image tag.
<CFQUERY datasource="MYDSN" NAME="GetDocs">
SELECT Record1, Record2, Record3, Image
FROM tbl1
</CFQUERY>
<cfoutput>
<img src="whateverdirectory/ImageFolder/#Image#>
</cfoutput>
This would output in the HTML as:
<img src="whateverdirectory/ImageFolder/image1.jpg>
Hope this helps,
