Scaling an Image

True Image.

Code	Result
`<img src="images/world.jpg" width="137" height="145" alt="True globe" border="0" />`

Double size. What happens when you scale up? Pixilation occurs and the image quality looks poor.

Code	Result
`<img src="images/world.jpg" width="274" height="290" alt="Bigger globe" border="0" />`

Double width, half height.

Code	Result
`<img src="images/world.jpg" width="274" height="72" alt="Squished globe" border="0" />`

Scaling to half size. The image quality is fine, but this is not recommended. Why not? Consider file size and download time.

The original file world.jpg is 14.5KB

Code	Result
`<img src="images/world.jpg" width="68" height="72" alt="Incorrect thumbnail" border="0" />`

This is the correct method. Resize the image in your graphics editing software to half size.

The new, reduced size file worldsm.jpg is 2.2KB. This is a major reduction in file size and download time savings. Notice that reducing an image's dimensions by 1/2 reduces file size 4 times smaller or more.

Code	Result
`<img src="images/worldsm.jpg" width="68" height="72" alt="Thumbnail" border="0" />`
