G2/Joomla: Image Block link & wrapping. embedded.php??

Hello, I'm using Joomla 1.0.11 and G2 2.1, latest ver. of all Bridge modules and components. I have 1 image block problem and a few other related issue.

The image block does pull an image from my gallery and display it, although if that image is clicked on, it tries to open a page which doesn't exist.

Example: A link it gives me would be:
http://mydomain.com/v/USA/ColSand04.jpg.html,
but the link that opens that image should be:
http://gallery.mydomain.com/v/USA/ColSand04.jpg.html

There is another issue I have. I'm running G2 standalone with the PGTheme. It's a nice theme with floating information boxes, but looks bad when wrapped. All the features of PGTheme obviously don't adapt well to integration. That is fine by me, as I'd like to keep this theme in a stand-alone version.

However, I notice that the link to G2 as reported in the Bridge Admin component is http://gallery.mydomain.com/embedded.php, instead of .../main.php.
I guess this is a function of the bridge, I am not sure. But is there an option to run the bridge either wrapped or unwrapped? I did not see any option for that in the newest bridge version.

These questions are probably all related:
If a user links to G2 through the bridge it is always wrapped, going to that /embedded.php page I guess. Then they are logged into G2 but it looks bad with PGTheme wrapped. Can I have the bridge log them in unwrapped, and they will still be logged in, or will they have to access G2 standalone and log in separately every time? In other words, does the bridge ONLY work (log them into G2) in wrapped mode?

Also, since the component link seems to point to that .../embedded.php page, is it possible I can have 2 different themes working, depending on where the site is accessed from, so that the wrapped page coming from Bridge will have a more integrated theme while the standalone site can keep PGtheme?

Here is what G2 reports I am running:
