Convert file extension on the fly

[Information Team]

Using Valetina DB and Impressario PDF
I need to convert the file extension of *.swf files to *.jpg

I am getting the data from a table using an repeat element that spits out a 
list of files
all the paths are swf file.
So where ever there is a SWf file I need to correlate to an image file that 
is associated with the swf file.

Convert
["*.swf"]


To


["@/templates/flash/images/*.jpg"]

Thanks

Newbie
