Table spills off page in some browsers

I have tables with linked images, and they look great in Chrome and Safari. However, they spill off the right side of the page in Firefox, IE and Opera. How can this be fixed?

We have visited your website the problem is occurring due to any one of the plugin you are using, Deactivate all plugins one by one and checkout which plugin creating this problem.

 

Thanks for your reply. I deactivated my plugins one by one, refreshing each time. The issue was not resolved. Any other suggestions?

 

Problem wasn't the plugins. I had to send them an e-mail directly (though they answered that quickly) to get a response. Told me this was something I would have to hire a developer to do. Can't fix everyone's weird problems.

 

Hello,
I have seen your website and found that it is working fine in Firefox, IE and Opera web browser.

 

Yes. I paid to have it fixed. Thanks.
