When I add an image to a post with the MarsEdit Media Manager, it sets the "alt" attribute to the text I enter into the Media Manager dialog, and it sets the "title" attribute to the filename.
Browsers show the image's title as the mouseover tooltip, not the alt text. But the filename isn't a very useful tooltip, whereas the alt text might be useful. So I'd prefer that the Media Manager either doesn't set the title attribute, or sets it to the same value as the "alt" text.
What do others think? Is there a MarsEdit preference I don't know about for changing this behavior?
