Make the Title Picture in an arcticle 'optional'

Hi, we are using the Gallery View for some of our Categories. While this is a nice feature it also has a downside. The format of the Picture used for the Gallery is a different format than something you would use as a title in an article (see above). I cant use the Title as an Icon and I cant use the Icon as a title.
It would therefore be great to have a small tickbox in the Top Picture to decide that this picture is 'icon only' and then does not get shown in the article...
