This plugin integrates OptiPNG with Paint.NET. It optimizes PNG to make them smaller, which is good for web use.
OptiPNG is a PNG optimizer that recompresses image files to a smaller size, without losing any information. This program also converts external formats (BMP, GIF, PNM and TIFF) to optimized PNG, and performs PNG integrity checks and corrections.

Here is the icon and cursor format plug-in for Paint.NET
The plugin is awesome, it supports editing and saving images to be used as cursors also. And both formats, icons and cursors, can be saved with multiple image sizes in one file to support multiple icon and cursor sizes. While it is overkill for my application, this feature will save time in the future by allowing icons and cursors to be designed once (as a larger image) before being automatically scaled to each of the smaller sizes. The same feature addresses large icon and cursor sizes for users that require higher accessibility (another extremely important aspect of software development that is far too often ignored) making this plugin an all-in-one hit.
