The Before & After Image Viewer is a unique flash application that allows you to place two images on top of each other, and by selecting the slider-bar the viewer can hide and reveal each image allowing both images to be compared without placing them side be side.
I built the Before & After image viewer with the intent to help showcase a recent makeover (before and after), to aid in comparing two products, highlighting photoshop skills (untouched and photoshopped image), or to simply use it to communicate a message in a dynamic way.
Just about everything in this flash application is customizable through the use of flashVars: Title, description, horizontal or vertical bar, solid or faded bar, colors, positioning, the images, etc. This means no flash or actionscript knowledge is required. In fact you can use the file without ever opening the FLA (unless of course you wanna get your hands into the source).
The Before & After Image Viewer is also capable of handling just about every file format you can throw at it (jpg, gif, png, swf).
