well, you are quite close! :-)

This is form the button script, right?
Lets call it Button "bildbutton"

...
    set the ImgCollectorProp of me to ImportImage
    ## ME  = button "bildbutton" in this case!

    set the ImgImportProp of me to ImageCollector
    ## Correct so far, but now that are the buttons custom properties!

     modal stack "ImageTypSelector"
...

So you have to query these custom properties like this:

on preopenStack
   get the ImgImportProp OF BTN "bildbutton" OF CD X of stack "Karten"
   put it into fld "Imgname"
   get the ImgCollectorProp OF BTN "bildbutton" OF CD X of stack  
"Karten"
   put it into fld "ImgList"
end preopenStack

that will do the trick :-)


OR, if you want to use the custom properties of that stack:

...
    set the ImgCollectorProp of stack "Karten" to ImportImage
     set the ImgImportProp of stack "Karten" to ImageCollector
     modal stack "ImageTypSelector"
...

then your "preopenstack" script above will work.
