This would be a good place to use a CSS class.

In your CSS file (or between <style> tags that you put in the HTML 
header), you can write something like this:

.right { float: right; border: 1px solid brown; }

And then for the individual right-floated images, you can write:

#+ATTR_HTML: :class right :alt foo

Using :class here is both more readable and more maintainable: 
there's just one place to update your style code if you want to 
change how the right-floated images display.

Hope that helps!
