[TYPO3-RTE] allowing align atribute for img tag

[Lukas Stancik]

Hi guys,

I'd to kindly ask you for your help. I need to have <img> tag with corresponding align attribute set rendered in frontend. So far I have only eg. style="float: right;" set for the image tag if I chose 
right-align in the insert image dialog, but I need also align="right" in this case. Is it possible to configure RTE to behave such way? I've searched and read tons of docs about RTE settings but I'm 
getting a bit lost :)

Could you please advice? Thank you very much in advance.

Best Regards

Lukas Stancik
