Can I update the Bootstrap 3 extension on my system to use the current css version ... 3.3.2? If so, where would I do that? I'm having issues with images being 100% of their div but if I use the maxcdn link they are fixed. Thanks.

Hello Kevin,
Could you please explain what exactly do you mean by: "I'm having issues with images being 100% of their div " ?

Here's a discussion on the subject that may help explain better than I can ...
github.com/twbs/bootstrap/issues/13996
I found another discussion that mentions this issue being corrected or reverted back and it refers to Bootstrap 3.3.2. If I link Bootstrap's css via maxcdn instead of to my local styles generated by the extension the stretching of my images is corrected.
I prefer to link my css locally and so I'm wondering if I can replace the css file that gets generated by the extension with the updated version so I don't have to modify anything after creating a new Bootstrap site.
I hope this makes sense. Thanks Teodor!

Hi Kevin,
Yes, you can replace the file generated by the extension, with the one you need.

Thanks for the reply Teodor. Could I replace the css file within the extension itself? If so where would I do that. I'm on a windows 8 machine. What I'm hoping to do is replace the css file within the DMX extension, so when I create a new page and convert it to bootstrap 3, the new css is already in place. Thanks again.

Hi Kevin,
you can replace the css file(s) here:
C:\Users\YOUR_USERNAME\AppData\Roaming\Adobe\Dreamweaver_VERSION_\en_US\Configuration\Third Party Source Code\bootstrap3\css

Awesome, Thanks!
