Christopher Einarsrud was intended to develop a flash photo gallery called Polaroid Gallery for his online portfolio in year 2006, but he ended up going for something completely different. He thought that it might come in handy for someone else, so he decided to release it as a free and open source flash gallery for everyone. All the photos are displayed as Polaroid Photos, you can move them around with your mouse. You can also double click on each photo to zoom in. Polaroid Gallery looks so fresh and stunning that I would like to have one too.

As we know, the input with the type=”submit” is either too ugly (Firefox), a little buggy (Internet Explorer) or completely inflexible (Safari). The solution for most is to use image inputs and create the damn things ourselves. And it’s unfortunate, because then we’re reduced to the tedious tasks of opening up Photoshop every time we’re in need of a new button. What we need is something better—something more flexible and meant for designers. Lucky for us, the solution already exists. ParticleTree introduced us a better way to do it, also with mouseover and mouseout effect.
