A free and open source screenshot tool optimized for productivity
Greenshot is a lightweight screenshot software tool for Windows that quickly creates screenshots of a selected region, window, or full screen; you can even capture complete (scrolling) web pages from Internet Explorer. Greenshot easily annotates, highlights, or obfuscates parts of the screenshot. Greenshot also exports screenshots in various ways: save to file, send to printer, copy to clipboard, attach to e-mail, send Microsoft Office programs, or upload to photo sites like Flickr or Picasa. And Greenshot has a lot more options, to simplify the creation of, and work with, screenshots every day. Overall, Greenshot is easy to understand and configurable, that's why it is an efficient tool for project managers, software developers, technical writers, testers, and anyone else creating screenshots.

Simple and intuitive 2D vector drawing for electronics and not only.
A multiplatform vector drawing program with a complete library of electronic symbols. Schematics and drawings are stored in a very compact text format. There is no netlist concept behind the drawings (so no simulation, and this is a choice) but this allows a great graphical flexibility and ease of use, making FidoCadJ the perfect tool for exchange sketches in forum and newsgroup discussions with a few clicks. Drawings can be exported in several graphic formats, such as pdf. Follow the development live on Twitter: https://twitter.com/davbucci

Symmetric Sprite Editor
PartArt: Space is all about making higher quality spaceships quickly and easily. Simply select the parts you want, move them around using the buttons or asdwqe keys, and finally save your creation to your computer with a transparent background. Ships are compatible with commercial projects - just mention Skorpio. To make the saved images more useful, open them in GIMP, autocrop them, adjust hue/saturation to get the desired colors, and scale them down to the point that the seams are less visible.
Image editor / converter for MCU-based embedded projects
This editor mostly intended for image converting and preparing them for use in MCU-based projects. Program provide very limited set of paint functions, so if you want to make some graphics from scratch, maybe it will be better to use another image editor and copy-paste or import drawings to PixelImage. Maybe you'll be interested in a font editor for embedded projects: TFT Font Factory (https://sourceforge.net/projects/tft-font-factory/), my another project Modified tickets permissions: Now anyone can create ticket and post comments (pre-moderated).
Box is a language specifically designed to make vector graphics easy plus a integrated development environment which facilitates the use of the language by interactively showing the graphical output. Box combines the convenience of drawing figures with the mouse with the convenience of describing them with a language tailored for vector graphics.

Modification of the graphics program GIMP to replicate Photoshop feel
An upstream source site housing the original files for this mirror is no longer available. GIMPshop is a modification of the free/open source GNU Image Manipulation Program (GIMP), intended to replicate the feel of Adobe Photoshop. Its primary purpose is to make users of Photoshop feel comfortable using GIMP. It shares all GIMP's advantages, including the long feature list and customisability, while addressing some common criticisms regarding the program's interface: GIMPshop modifies the menu structure to closely match Photoshop's, adjusts the program's terminology to match Adobe's, and, in the Windows version, uses a plugin called 'Deweirdifier' to combine the application's numerous windows in a similar manner to the MDI system used by most Windows graphics packages. While GIMPshop does not support Photoshop plugins, all GIMP's own plugins, filters, brushes, etc. remain available
