Bug in Prestashop 1.4.4.1, to fix and upgrade to 1.4.7

Hello Website : [login to view URL] This is a project for a prestashop specialist : > Some bugs in the current version of prestashop not only but such as : 1/ Not all images are appearing. Images are stored in a folder within the server. Need to have all images appearing 2/ google checkout module is not working properly (order in google checkout but not in prestashop back end), We have fixed it but lost some data. We have both module files (old working well, and new not working well), and should be very easy and fast to fix. 3/ Upload new product normally 4/ adding shipping carriers 5/ adding/editing countries we ship to 6/ home page, and slideshow uploaded 7/ images uploaded from the back end (location of the files, the way these images are organized in the server) 8/ Some html codes to add to the home page, such as G+ icon... We need to have the website upgraded and that prestashop features work properly, without any bug, and without damaging the current modules that are working well. The current version had some code changing, especially in the area of uploading images of the products for the website. So we need to get it working as the original prestashop version works . Good Luck & Happy bidding :)
