 # set PL  {bild01.jpg bild02.jpg bild03.jpg} 
 ##
 # set P1 "http://blah.de/fasel/"
 # set P2 "bild01.jpg"
 ##
 # set url "http://blah.de/fasel/bild01.jpg"

   set P1 "http://blah.de/fasel/"
   set PS {bild01.jpg,bild02.jpg,bild03.jpg} 
   puts "# PS=$PS."

   set PL  [string map -nocase { "," " "} $PS]
   puts "# PL=$PL."

   set i 0
   foreach P2 $PL {
     incr i
     set url "$P1$P2"
     set filename "XY_$P2"

   # puts "$i.   URL=$url."
   # puts "filename=$filename."
     puts $url
   }
