I am want to display images from the MLS on my website.Downloading all the images and then uploading them to my server is a waste of time. Each listing has a different # of photos. The only thing that changes is the subdirectory for each photo.

http://http://www.sancapmls.com/san/jpg2/mls_number.jpg
http://http://www.sancapmls.com/san/jpg3/mls_number.jpg

Is there a to check for the existence of the photo? I tried the following and obviously it was the incorrect approach:

<cfif FileExists("http://www.sancapmls.com/san/jpg2/#MLSNum#.jpg")>
            <img src="http://www.sancapmls.com/san/jpg2/#MLSNum#.jpg" />
</cfif>

 FileExists would take the physical directory, not the URL

So this ..
<cfif FileExists("http://www.sancapmls.com/san/jpg2/#MLSNum#.jpg")>

Would be something like this...

<cfif FileExists("c:\inetpub\wwwroot\san\jpg2\#MLSNum#.jpg")>

That won't work, hence my question. The files I am trying to pull are not on the same server as the website where I want to display them.

I missed the "image on another website" in the title..

 You can use <cfhttp>  to pull the image over, if its not there, it will return an error code.
