Simple photo gallery website for personal use

Hi Expert, I want a basic photo gallery website for my baby sons domain name. It can be open-source or whatever but must do the following: Upload Jpegs of any size ( resizes them and creates thumbnails on the server side ). Upload lots of Jpegs at once. Add descriptions (easy) and create categories. Must be easy for a visitor to view the photos / slider. Must look nice / modern and be compatible with all modern browsers. The host account is linux. When bidding please mention what gallery software you intend to use so I can evaluate. Thanks.
