The document provides instructions for making backgrounds of graphics transparent in Adobe Photoshop CS5. It describes five methods: 1) Setting the background to transparent when creating a new file, 2) Unlocking and changing the background layer type to normal to allow transparency, 3) Using the eraser tool to make selected areas transparent, 4) Using the magic eraser tool to make contiguous areas of the same color transparent, and 5) Saving the file as a GIF to maintain transparency when exporting for web use. Figures and step-by-step descriptions are provided for each method.
