I assume you got this from here and if you look at the comments there seems to be the same issue you are mentioning. The author suggests adding the preloader script as in the demos.
Add this to the end of the html and see if it fixes it for you.
Hi Paul… I am very happy you took time out to spot this! I actually paid another develop to do this so i have no idea where the template came from but thank you again for spotiing this. i’ll apply the fixes at the weekend.
No worries if you have no time to reply to this but can you able to check if ive done everything right? Thing id the hoem page images when in firefox somethimes do not appear when your in another part of the site say http://www.davidclick.com/packages.html and then after a good 10 seconds navigate back top the home page:http://www.davidclick.com/index.html no images. Butthey appear when you do a hard refresh
I know replies are volunary so if you have no time no worries, i’m chassing the developer who I’m sure will be able to fix it!
