Problems with IE 6 and 7

Ok, I am done building my site after using the Dark Atlantica Wp theme. However for some reason my sliders/ gallery (PrettyPhoto plugin ) and blog page is not showing up in IE 6 and maybe 7. But it works fine on my IE 8 and firefox. I tried uninstalling and reinstalling the theme. But that did not help. I have couple plugins and flash on it so I am not sure if one those things caused the problem. Please can anyone help. I am almost done with the site except for these issues and I am still new to these things. I did try validating the site but I can’t tell what is the issue by that. Here are the links with the issues. https://www.journeyofablackearedkite.com/galleries/indonesia/ https://www.journeyofablackearedkite.com/blog/ https://www.journeyofablackearedkite.com/about-2/
