PS
Can anyone tell me why in the following code the variable href_preview is always empty?

The XSL file:

>why in the following code the variable href_preview is always empty?
It is not.

Only this condition is never met
><xsl:if test="$width != '' and $height != '' and $href_preview != '' and $href_quicklook != ''">
simulataneously for the four variables at the same time.

Maybe you have to re-think about the "and" and "or" in the conditional.
