Hi Jeff, The CF Server won't catch the param though unless you tell it to process calls for .gif files right? CF (I don't think) is not going to process the img src that is a .gif is it?
I say this because in the past I had taken over a site and needed to add some code to each file that already existed, I had to tell CF to process .html files to do it (I had tons of existing html files that needed to go through CF), wouldn't you have to the same thing? >Same approach for images as links. > ><img src="http://yahoo.com/logo.gif?track=UNIQUE-PARAM-FOR-USER"> ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~| Adobe® ColdFusion® 8 software 8 is the most important and dramatic release to date Get the Free Trial http://ad.doubleclick.net/clk;203748912;27390454;j Archive: http://www.houseoffusion.com/groups/CF-Talk/message.cfm/messageid:309117 Subscription: http://www.houseoffusion.com/groups/CF-Talk/subscribe.cfm Unsubscribe: http://www.houseoffusion.com/cf_lists/unsubscribe.cfm?user=11502.10531.4
