my website is thepartypaparazzi.net none of my galleries seem to be loading all the way. you can only view about 6 pictures and the rest wont preload or will be displayed as Xs. My webhost has said it isnt a server problem so i'm wondering if its the script? its been working fine for about 8 or 9 months then out the blue this started happening! Also looking to upgrade to 1.9 (currently 1.8.5), need instructions on how to install

thanks in advance you guys this would be a big help if someone could give me a solution!
