Hi all,

Ok, I was easily able to solve the problem, but logically, I don't understand
and I would appreciate if somebody could quickly explain this to me.

I'm using a a function that determines the size of an image. The size will
determine the size of a pop up window, when the thumbnail is clicked. So, I did
this:

<cfoutput query="whatsNewpaintingsThumb" maxrows="50">
  <cfif columnCount EQ 1>
      <tr>
  </cfif>                             
  <cfset lImageSize =
ImageSize("D:\xxx\xxx\images\paintings\#paintingImgLarge#")>
  <td>
      <a href="##"
onclick="MM_openBrWindow('wNewPaintingPopup.cfm?id=#id#','','width=#lImageSize.I
mageWidth#,height=#lImageSize.ImageHeight#')"><img
src="images/paintings/#paintingImgTiny#" border="0" /></a>
  </td>                      
  <cfset columnCount = #columnCount# + 1>
  <cfif columnCount EQ 5>
      </tr>
      <cfset columnCount = 1>
  </cfif>
</cfoutput>

When processing the query, the first query result (row) runs through without a
problem. On the second result the code brakes though, with an error mentioning
something about invalid symbols for the function. When I do the same thing with
a loop it all works properly.

<cfoutput>
  <cfloop query="whatsNewpaintingsThumb" endrow="50">
      <cfif columnCount EQ 1>
          <tr>
      </cfif>                             
     <cfset lImageSize =
ImageSize("D:\inetpub\japingka\images\paintings\#paintingImgLarge#")>
     <td>
          <a href="##"
onclick="MM_openBrWindow('wNewPaintingPopup.cfm?id=#id#','','width=#lImageSize.I
mageWidth#,height=#lImageSize.ImageHeight#')"><img
src="images/paintings/#paintingImgTiny#" border="0" /></a>
      </td>                      
      <cfset columnCount = #columnCount# + 1>
      <cfif columnCount EQ 5>
          </tr>
         <cfset columnCount = 1>
     </cfif>       
  </cfloop>
</cfoutput>

Now, I did read during my investigation that the setting of the variable

     <cfset lImageSize =
ImageSize("D:\inetpub\japingka\images\paintings\#paintingImgLarge#")>

will in the cfoutput fail. But it wasn't really mentioned why. So, ahm, can
somebody explain this to me? I'd just like to understand.

Thanks
Adrian
