Hey Lynn,

     Not sure if this is what you ask for - I am passing query values as parameters in the view here

#Sample Function in controller
def showmyimage():   
   # Some db query you want to see data for
    displayimage = db.tableName(request.args(0,cast=int)) or redirect(URL('index')) 
     
    return dict (dispimage=dispimage)

In view - showmyimage.html

<!-- you can utilize it in this way - For example it is an image that you want to serve on the page. somephoto is the field name where image is uploaded or something -->

<img src="{{=URL('download', args=displayimage.somephoto)}}" />

Just place your function in the module and import it in the view
