It’s the way the jQuery slideshow plugin works.
One of the parent divs of the image is assigned a width through inline CSS styles. This width is based on (the width of) its contents — so, the plugin checks how wide the image is and then assigns that width to the parent div.
I’m no jQuery expert, but I can see why IE has a problem with it. It detects the width of the content (the image) as 796px (or whatever the original width of the image is) and then applies that to the parent level. Which is why a div like .views_slideshow_cycle_div_sponsorbox-panel_pane_1_2 has that width, and so the image inside of it, set at 100% max, will also have that width.
For other browsers, it works differently. The container cell of the slider is set to 34.043%, so the child divs are also set to something like 250px (more or less), and the image (set as 100% max) is therefore also set to that. And that’s the width detected (and applied to the parent level).
SOOOOOO…..
IE’s process:
1. take original image width (result: wide)
2. apply this to the parent div (result: wide)
3. set image to 100% of parent div (result: wide)
Other browsers:
1. set image width to 100% of parent div (result, 34.043% of full site, app 250px)
2. take image with (result: 250px;)
3. apply this to the parent div (result: 250px)
tl;dr — it’s probably more of an issue with the plugin than with IE itself.
