Here is how I do it
<!--- First check for a count in a special dir and return it as a record
count --->
<CFIF NOT IsDefined("Session.RandNum")>
<CFSET PATH = ExpandPath("images\life_care_rand")>
<CFDIRECTORY ACTION="LIST" DIRECTORY="#PATH#" NAME="rand_dir">
<CFSET Session.RandNum = RAND_DIR.RecordCount - 2>
<CFELSE>
<CFSET Session.RandImageNumber = RandRange(1, Session.RandNum)>
</CFIF>
<!--- In line in your code you just output the image name --->
SomeImageName#Session.RandImageNumber#.jpg
Each time the page is refreshed the session is renewed with a new number.
You only have to get the number in the dir once.
Hope this helps some.
