Admin SSL & Nextgen-gallery after recent update

Hi!

I’ve found a problem with plugin, and can’t find a solution.

On all WP sites I switch on Force Admin ssl option (wp-config.php).
And my hosting server have self-signed certificate for ssl.
After recent plugin updates on Safari and Chrome browsers appears a problem. Gallery not display some images on the LightBox window (lightbox-btn-close.gif etc)
Firefox show warning and works perfect if certificate is confirmed.
If certificate wasn’t confirmed by user images not displayed.

For example. If you look at page source you can see that script

/* <![CDATA[ */

nextgen_lightbox_loading_img_url = "https:\/\/www.dzyn.cz\/wp-content\/plugins\/nextgen-gallery\/products\/photocrati_nextgen\/modules\/lightbox\/static\/jquery.lightbox\/lightbox-ico-loading.gif";
nextgen_lightbox_close_btn_url = "https:\/\/www.dzyn.cz\/wp-content\/plugins\/nextgen-gallery\/products\/photocrati_nextgen\/modules\/lightbox\/static\/jquery.lightbox\/lightbox-btn-close.gif";
nextgen_lightbox_btn_prev_url = "https:\/\/www.dzyn.cz\/wp-content\/plugins\/nextgen-gallery\/products\/photocrati_nextgen\/modules\/lightbox\/static\/jquery.lightbox\/lightbox-btn-prev.gif";
nextgen_lightbox_btn_next_url = "https:\/\/www.dzyn.cz\/wp-content\/plugins\/nextgen-gallery\/products\/photocrati_nextgen\/modules\/lightbox\/static\/jquery.lightbox\/lightbox-btn-next.gif";
nextgen_lightbox_blank_img_url = "https:\/\/www.dzyn.cz\/wp-content\/plugins\/nextgen-gallery\/products\/photocrati_nextgen\/modules\/lightbox\/static\/jquery.lightbox\/lightbox-blank.gif";
/* ]]> */

There https prefix is invalid. Must be an http.

Thank you a lot for a good plugin!
