I've come across a strange conflict between Twitter Bootstrap (2.2.1) and Ad-Gallery in Internet Explorer.
It seems that certain lines in bootstrap.min.css are causing issues, preventing images from displaying:
img{max-width:100%;width:auto\9;height:auto;vertical-align:middle;border:0;-ms-interpolation-mode:bicubic;}
By removing the following two lines, everything works fine:
width:auto\9;height:auto;
However, instead of removing those lines altogether, I've been attempting to override them without success using these approaches:
.ad-gallery img{width:default;height:default;}
.ad-gallery img{width:none;height:none;}
.ad-gallery img{width:auto;height:auto;}
Is there a way to successfully override these properties?
By the way, there are no issues with Google Chrome and Mozilla Firefox. You can see an example with the original Bootstrap min CSS file here, which is not functioning correctly.
Here is a working example with a modified version of bootstrap-modified.min.css here.
