I am using the NextGen gallery with the thickbox effect. I have a couple of issues:

1. the images look really really bad / pixelated in IE7 (they are high quality images), so is there a way for me to either apply a different effect just for IE or stop the thickbox from working in IE?

2. can I change the thickbox color from white to black? I have done several searches but haven't found a good answer.

I am using Atahualpa 3.6.7 and WP 3.1.4 and my site is http://www.alexiscoram.com

THANKS!!

1) have you swapped to twenty ten to see if it is theme related?
2) are they ok in other browsers?

Yes, they look fine in all other browsers. I started reducing the file sizes for upload and it looks a bit better but still not very good.

If I switch the theme will all of my Atahualpa changes be maintained?

You could perhaps try using a "lightbox" plugin such as Shadowbox JS or Easy Fancybox to see how they work.

Nice suggestion, Larry. I had tried a few previously but none that worked properly. Easy Fancybox is working well and definitely improved the IE quality. THANKS
