GIF - well suited to limited color images - no loss in compression. Use these for line images, technical drawings, etc
JPG - well suited to photographs - image can be highly compressed with minimal distortion. Use these for photographs.
• Digital cameras will permit image capture and storage - images in JPG format are best.
• Scanners will capture images, but this is a poor alternative as the image sizes are larger and image quality is poorer
- Photographs tend to become grainy when scanned.
- Line drawings become blurred.
• Screen captures are also possible, but do these with a lower color resolution on the screen (256 color mode).
