Is there a way to turn off auto style="width: ; height: ;" on images added to the text editor?
The short answer: no.
The long answer: there are work arounds. but it requires a few lines of programming.
Does it really matter, is it causing problems?
Ole
It makes every image too small, so yes, on this project it is causing problems.
How can i work around it?
You can filter the HTML in the "BeforeUpdate" event in the partial code file of the contentclass.
