The Image editor (View | Toolbars | Image Editor) has an extensive set of tools for creating and editing images, as well as features to help you create toolbar bitmaps. In addition to bitmaps, icons, and cursors, you can edit images in GIF or JPEG format using commands on the Image menu and tools on the Image Editor toolbar.
With the Image editor, you can:
The Image Editor window shows two views of an image, with a split bar separating the two panes. You can drag the split bar from side to side to change the relative sizes of the panes. The active pane displays a selection border.
Using the Image Editor, you can view 32-bit images, but you cannot edit them.
Visual Studio Image Library
Visual Studio ships with an Image Library containing many animations, bitmaps, and icons that you can use in your applications. The Image Library is installed at \Program Files\Microsoft Visual Studio 9.0\Common7\VS2008ImageLibrary. Consult the ReadMe that ships with the Image Library for guidance on how to properly use the included animations, bitmaps, and icons.
You can use the Image editor and the Binary editor to work with resource files in managed projects. Any managed resources you want to edit must be linked resources. The Visual Studio resource editors do not support editing embedded resources.
For information on adding resources to managed projects, please see Resources in Applications in the .NET Framework Developer's Guide. For information on manually adding resource files to managed projects, accessing resources, displaying static resources, and assigning resources strings to properties, see Walkthrough: Localizing Windows Forms and Walkthrough: Using Resources for Localization with ASP.NET.
