ignoring SSL and using unsecured images.

The plugin keeps calling images from https://a0.twimg.com/profile_images/…… and not https://
even though all javascrits, css files and basically the rest of the page is more or less covered under https://

Any ideas why this could be or what i could try to do to solve it.
in the .js file on line 32 it also says https: first.
