While I have presented the new solution to two parties, I realized that the rule to match the css selector of the current image should be defined as a css selector too.

This is even more important as we target to parse the css file to make the rule definition obsolete.

Since this is a very isolated feature and I have written the necessary tests I will commit this for the 1.1 final (resp. rc2) version. There were any API changes (only one class added).
