In reaction to the www.joomlaworks.net/forum/simple-image-gallery/14113-re-center-the-gallery discussion I'd like to ask and propose for something different.

I use the "display_mode" option 'single thumbnail mode' quite a lot. In single thumbnail mode I would love to be able to right align (flush right) the thumbnail with the surrounding text wrapping around it.

Can you provide some option to accomplish this??

Ok, so today I planned to make a nice template override for the SIGPro single thumbnail mode I use. But I don't see the plugin in the list of Plugins I can create an override for? Can you give me some guidance on how to do this?

Ok, thanks, I'll manage with the MVC function, thanks!

But then, I first have to find what exactly to change. I tried 545483 ways to find what parts of the CSS I have to edit, and I give up. Normaly I know my way around with the CSS's, but not in this case. Could you help me a bit more? See this test example:
www.nietap-terheijl.nl/buurtschap-nietap-terheijl/activiteiten-vd-buurtschap/139-hoantie-op-n-stokkie
It displays an article with three galleries in single thumb mode. I'd like to be able to arrange them in one row next to eachother, instead of on top of eachother. I really edited and/or deleted all floats, widths, and whatever I could come up with but don't get it right... Now if you use the developer options in Chrome (or any other browser) what CSS modifications make it work?
