Media gallery – another question

Hi,
just another question regarding new media gallery introduced in in version 0.18.5. Is it possible in anyway to disable transparency. I know you already helped me with that update to Tainacan suppport for Blocksy plugin where I could change background from black to white and I am really (REALLY) grateful , but is is possible in the same way to enable/disable that transparency when we are using the media gallery. The backgound of the media is white but it is also a bit transparent.

I would also like to remove that strip at the bottom of the media viewer with the info about the image, if it is possible. I know that all those options are features, but sometimes, it would be nice to have an option to enable/disable things. ??

I know I maybe pushing the envelope here ??

thx
Vedran
