Javascript image gallery with horizontal scroll bar

Hello everyone, I am a web designer and I need a web developer to help me with the following small project: I need a photo gallery EXACTLY like the attached file (same colors, same scroll bar size,…). Another important thing is that the gallery must be easily customizable, this means I can replace the pictures, add more or remove some. 7 products at a time but if this will be customizable as well would be great. (- - - - please insert comments to help me understand how I can custize it, width, height, …- - - - ). The designer that will win the project will be the one able to proof to me that he can make it and that will quote the lowest. I need that all revisions are included in the quote. Final file to be delivered as a .zip (or .rar) folder with an html page of the gallery inserted in a div, relevant css and javascript. If I will be happy with this one I will be happy to give you more project in the future as actually I am looking for someone who can help me with similar staff as well as php. Thank you Alessia
