You don't actually need the loop at all. Remember that you can access a query using indexed notation - so the above could be written as: <cfset randImgRow = randRange(1, getRandImage.recordcount)> <cfoutput><a href="/album/default.cfm?albumid=#getrandimage.album_id[randImgRow]#"><img src="/images/album/#getRandImage.thumbnail[randImgRow]#" alt="#getRandImage.caption[randImgRow]#" class="thumbnail"></a></cfoutput> Of course both solutions do the exact same thing and both access the query... I wouldn't be surprised to find them both about the same performance-wise as well. Mine is really just a little less code. I cover this in more details in my "Guide to CFML Variables" here: http://www.depressedpress.com/Content/Development/ColdFusion/Guides/Variable s/NotationIndexed.cfm Don't get me wrong tho' - I agree completely about "informational" posts like this. I wish more people would throw up snippets when they get something to work. ;^) Jim Davis ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Find out how CFTicket can increase your company's customer support efficiency by 100% http://www.houseoffusion.com/banners/view.cfm?bannerid=49 Message: http://www.houseoffusion.com/lists.cfm/link=i:4:219554 Archives: http://www.houseoffusion.com/cf_lists/threads.cfm/4 Subscription: http://www.houseoffusion.com/lists.cfm/link=s:4 Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4 Donations & Support: http://www.houseoffusion.com/tiny.cfm/54
