1. What's the difference between GIF and JPEG?

• Consider the Number of Colors in the Image
• GIF and JPEG are the two most common image formats on the WWW.  JPEGs are capable of displaying images that have millions of colors in their palette, while GIFs can only display 256 colors in an image.  Therefore, JPEGs are particularly good for displaying photographs and real world images, or perhaps even some computer-generated images with complex color schemes. 
• Photos and Images with Complex Color Schemes:JPEG is very good at compressing a broad color spectrum.  GIF is limited to only 256 colors.
• Graphics with Relatively Simple Color Schemes: As the number of colors in an image's palette approaches or surpasses a GIF's maximum of 256, JPEG, with its powerful compression capabilities, becomes a wiser choice. But with a simple color scheme, GIF provides a small file size without necessarily sacrificing image clarity.  
• Features:
• While JPEG are static images, GIFs can be animated.
• Also, you can designate one color in a GIF as transparent, so that whatever is behind that color s hows through the image.
