Is it all possible to show smaller size of the actual images in the thumbnail view?

Would it be something I can configure in com_comprofiler/plugin/template/xxx/template.css?

Max thumbnail height & width under CB tab setting for the Profile Gallery plugin does decrease the dimension of the thumbnail, but overflow seems to be set hidden.

Yes I changed my profile layout so it's going to need smaller thumbs. I changed the thumb settings but the original thumbs are the same size as before and extending beyond the placeholders for them...

I'd like a button similar to what you have in G2 which would be "recalculate thumbnails" or something like that.
