[Joomla G2 Bridge] Picturelinks do not open un-embedded

Hi,

I´ve got a problem with the gallery2 bridge for Joomla. I put it on my website to show a random image and all seems to work fine.
But the thing is, that when I click on the picture it opens embedded in my Website, so it shows up in the main contentpage. But I want it to open
in the normal gallery view outside my Webpage. And yes, I set the link-target in the settings of the bridge to "_blank", but this just resulted in opening a new browserwindow of my website with the picture embedded.
Since that didn´t work I tried it with the Imageblock external call (you know, something like gallery2/main.php?g2_view=imageblock.External&g2_blocks=randomImage&g2_show=title ) in the wrapper module of Joomla and it worked exactly as I wanted. But only with Firefox. The IE7 showed me a white frame around the picture with at least 20 pixel width, FF2 showed this frame too, but with the right backgroundcolor. The best would be to get rid of this frame, but I would also appreciate the possibility to change this color for IE7.
If anyone knows how to solve these problems please let me know.

Thanks a lot and merry christmas.

kind regards
