ideas for fixing #9

Hey, sorry I don't have a proper test environment ready, but I have some ideas to fix issue #9.
I'm mostly getting rid of the IMG tag and letting the A handling all this.

Makes me `display:block` the A though, so you might want to add a wrapper div.
But this would allow for some CSS effects and tooltips.

Please let me know the contribution policy, feature-branches etc...
I just wanted to submit the idea for you to validate or find new paths towards the fix.
See you,
