Here's a quick tip for those using Eclipse / CFEclipse, and would like to view images in your project from within eclipse.

Go to Window » Preferences in the Eclipse menu. Then expand General » Editors and click on File Associations.

This dialog lets you tell eclipse which editors should be used for a specific file name or file extension. Add a file type for *.jpg then click the Add button on the bottom for Associated Editors, and select Internal Web Browser.

You can repeat the steps for other file types such as png and gif.

In addition you can also add external editors for the image such as Photoshop, or whatever.
