Mosaic: Handling of Images-/Files in Tiles

Sorry for activating this old topic, but I realized that the old image tile way has some more advantages especially for pre defined content layouts, where you want to have images as place holders and want to allow the user just to change the image but not the size or the location of the image. With the richtext tile we can prevent the moving but can not have pre defined fixed sizes. That would be really help full.

I opened an issues for that here: https://github.com/plone/plone.app.standardtiles/issues/104
Help on that is really welcome.
