algorithm needed for placing thumbnails

Hi, For a thumbnail-gallery I need someone who can deliver algorithms for placing the thumbnails. The thumbnails have different sizes, some of them will be 50x50 pixel, some of them can be 400x600 pixel. They need to be placed on a desktop with a specific size (e.g. 768x1024 pixel) without touching each other and by maximizing the use of the desktop-space. So, on each page I want to be placed as much thumbnails as possible. Please only bid if you have experience in this field and can show me some work which goes in this direction. Thanks. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Installation package that will install the software (in ready-to-run condition) on the platform(s) specified in this bid request. 3) Exclusive and complete copyrights to all work purchased. (No GPL, 3rd party components, etc. unless all copyright ramifications are explained AND AGREED TO by the buyer on the site). ## Platform win
