Usually this is a digital image taken by the host operating system or software running on the computer device, but it can also be a capture made by a camera or a device intercepting the video output of the computer.

Full Screen is an extension which provides a fulscreen button on the toolbar.

Adds Full Screen toolbar button and context menu command.

After installing use View / Toolbars / Customize... to add the button to the toolbar.

reset-screen is a very simple Qt 4 program that displays a simple cross hatch pattern on your monitor.

Why is this useful? Well, it makes the auto-sync feature of the flat panel LCD monitors out there both faster and more accurate (well, for mine anyways).

I have to run this every other time I start KDE so I figure others may find it useful as well.

This isnt really useful for laptop users I think, but you may need it. Who knows? :)

This is a very simple program, which a very simple build system.

Amarok Full Screen provides a full screen front end for Amarok.

The look can be changed by custom THEMES.

Show the Image is a Firefox extension that shows the largest image in the page.

A very simple extension that can be used to show the largest image on the page - what you want to look at - without all the banners and layout around it.

After installing the extension you can add a new button to the toolbar by right-clicking on the toolbar, clicking customize and dragging the icon into place.

Left-clicking the button (or pressing Control+Q) will take you to the largest image in the current page, left-clicking (or pressing Control+Q) again will take you back again.

Middle-clicking the button (or pressing Control+Shift+Q) will open the largest image in the current page in a new tab, middle-clicking (or pressing Control+Shift+Q) while looking at the image on its own will close the tab if more than one is open.

Right clicking the button will go through all the tabs to the right of the current one, displaying the largest image in each.

Right clicking on a link will give the option to "Show Image following this link" which will open the largest image found at that link in a new tab.

Firefox Showcase is an extension that provides a new way to manage tabs and windows by showing them as thumbnails in a single window, tab or sidebar.
Includes a find bar that will filter the thumbnails, and the capability to select the thumbnails in the same way you would select files in your system.
Main features:
- Support for Firefox 2 beta 2.
- "Only current tabs" mode: toggle with CTRL+U. Will show only the current tab of each window. Can be enabled by default.
- Added selection area, making it easier to select thumbnails with the mouse. Works exactly as any file manager.
- Thumbnail caching. If enabled, a small capture of the different tabs will be cached, and used by Showcase when invoked. Disabled by default, can be enabled in the "Advanced" settings tab.
- Full screen plugins are now detected, and will show an icon instead of trying to render the thumbnail. Specific icons have been added for PDF, Quicktime and Flash. Other plugins show a generic plugin icon.
- Showcase can now be invoked using Firefox command line ("firefox -showcase"). This is useful when used together with an automation tool like AutoHotKey (http://www.autohotkey.com).
- Added option to hide the tab bar while using Showcase sidebar.
- Find bar state is now synchronized in Showcase tab, so its not possible to have 2 find bars at the same time. Can be disabled if necessary.

- Added an independent version of Showcase for SeaMonkey ("SeaMonkey Showcase"). Also, solved the configuration panel problem, and the contextual menu actions that were not working.
- Solved Showcase sidebar title cosmetic bug when statistics where activated.
