Zenity (or alternative) with custom file selector

When I use zenity and type --file-selection, if spawns the default GTK file selector. The problem with that is, of course, the lack of image thumbnails. Considering that I want to make an image selection like that, it is a bit of a downside. Is there a possibility to force zenity to use something like nemo or nautilus as its file selector? Or something like qarma (it is a qt based rewrite of zenity). Can also be yad etc. Anyone got any alternatives?
