[Plugin: NextGEN Gallery] slideshows being squashed horizontally

For some reason, images are being compressed width-wise down to around 20px wide in IE7.

I am using a slideshow that rotates through the gallery, inserting them into my pages using the following shortcode…

[slideshow id=9 w=400 h=300]

Also, sometimes it doesn’t happen on every photo in a slideshow…just one or two…

Any ideas why this is happening?

Thanks,
Jeremy
