Freebie: 2 Free Photoshop plug-ins from fnord
j2k is a free Aobe Photoshop and After Effects plug-in set for reading and writing the JPEG 2000 file format and SuperPNG is an open source Photoshop & AE plug-in for using PNG files.
SuperPNG has more comprehensive support for the PNG format than Photoshop's included plug-in and provides control over alpha channel handling.
PNG is an open source file format that supports tight lossless compression. It can be read on any platform by most graphics applications and is fully supported by all modern web browsers.
j2k reads and writes the JPEG 2000 file format, the successor to JPEG. Also known as JP2, JPEG 2000 uses wavelet compression as opposed to the DCT compression used in standard JPEG. The end result is better image quality in a smaller file. JP2 also includes mandatory metadata such as information about an image's color space.
The After Effects version has the ability to Auto Proxy, meaning that when working at half or quarter resolution, j2k will only need to read in a fraction of the file, resulting in dramatic speedups.
