Hello,
I would look at your script and fix any error I would fine. As far as the page loading slowing, that could be due to large image size files. Which would have to be an extra charge, because there is no way it can be done for the above charge. Upon reviewing the site more, I can make a better conclusion.
Let\'s start with the first error problem and take it from there.
Thank you and look forward to hearing from you!
