Yes, but how far do you want to go? 'background-image-brightness: -10', 
'background-image-effect: oil-paint'...

If these effects have to be done on the client side, then use SVG: wrap 
the image in one line of SVG and put an 'opacity' property on that. I 
think (hope) future browsers will allow inline SVG and MathML in HTML, 
so you don't even need to put the SVG in a separate file if you don't 
want to. The SVG renderer will be used even if the SVG is inline.

I don't think it is a good idea to duplicate functionality in different 
technologies (in this case CSS and SVG). Some overlap is OK, but not too
