Only real images can be projected since imaginary images only make light appear to originate from a point, light actually does pass through the real images location.

computer graphics, the transfer of pictorial data into and out of a computer. Using analog-to-digital conversion techniques, a variety of devices—such as curve tracers, digitizers, and light pens—connected to graphic computer terminals, computer-aided design programs, or optical scanners can be used to store pictorial data in a digital computer. By reversing the process through digital-to-analog conversion techniques, the stored data can be displayed in graphical form on a mechanical plotting board, or plotter, or on a televisionlike graphic display terminal. Raster graphics stores and displays images as a bit map, a series of closely spaced dots (or pixels) arranged in rows and columns. Vector, or object-oriented, graphics stores the images as mathematical formulas; images are displayed by calculating the coordinates of the end points and then drawing lines between them. Computer graphics capabilities range from the simple display of digital tabulations as line graphs and pie charts to complex animation and elaborate special effects for television and motion pictures. Computer graphics are used in architecture, art, computer-aided design, electronic games, flight simulators for pilot training, and molecular modeling.

You can use a software like MWSnap or SnagIt that can be used to capture a selected area of the screen and save it as an image file.

Raster:\nThe rectangular area of a display screen actually being used to display images. The raster is slightly smaller than the physical dimensions of the display screen. Also, the raster varies for different resolutions. For example, VGA resolution of 640x480 on a 15-inch monitor produces one raster, whereas SVGA resolution of 1,024x768 produces a slightly different raster. Most monitors are autosizing, meaning that they automatically use the optimal raster depending on the monitor's size and the video adapter's resolution. In addition, most monitors have controls that allow you move the raster, resize it, and even to rotate it. \n\n\nVector:\nIn computer graphics, a line that is defined by its start and end point.\n\n\n\nCheck out this site - http://www.ablesw.com/r2v/rasvect.html

Pixels (short for Picture Elements) are the smallest dots which make up an image.\n\nThe resolution of an image is a quality of how it is displayed. Windows PCs have a screen resolution of 72 DPI (dots/pixels per inch), while Macs have 92 DPI resolution screens. This doesn't affect much on screen (apart from the rendering of font point sizes), but when you print out an image it matters alot. A 1200 DPI images will have 1200 pixels printed per inch (1,440,000 pixels per square inch), while a 300 DPI images will only have 300 pixels per printed inch. The lower the resolution, the grainier the image will look when printed.

that would require an animated gif image. i don't beleive you can use anything but a jpeg.

A common garden variety TV screen is a Cathode Ray Tube- the screen itself is a phosphor coated glass surface attached to the vacuum bottle and electron gun assembly that makes up the rest of it. In operation the electrons from the gun at the rear of the thing are electromagnetically accelerated to the phosphor screen, and scanned by electromagnetic deflection back and forth over the phosphor, making little dots of light that cumulatively make the "picture"- each dot is a "picture element" or pixel the whole accumulation makes a recognizable image. and if you like I can explain how the thing work in color, too.

Print Screen or <prt scr> is a screen capture that records the visible items (except the mouse pointer)on the monitor or another visual output device to the computers memory.\n\nUsing the combination of <alt> <prt scr> copies only the active window to memory.\n\nYou must paste the contents of the clipboard (where the image is stored) to a graphics program.\n\nYou can use the <prt scr> while a video es playing in Windows Media Player. This will copy the image to a image editing program and allows the user to "edit" the video while it plays.\n\nThere are some programs like camtasia studio that capture not only a screen but a movie of the desktop or window.

Use google image search. \nHere's a nice one \nhttp://web.lemoyne.edu/~hevern/psy340/graphics/homunculus.jpg\nbut there are many others. Make sure to ask for permission, or see at the site if they support fair use.

Pretty much any imaging software will do this for you.\n\nIf you have a printer, scanner, web-cam, digital-camera or video-camera than it's likely that some form of imaging software was included with the package.\n\nWindows comes with MS Paint installed but this is a very basic program.\n\nAn excellent free program is Irfan View which amongst many other things, allows you to convert to and from many different formats.
