Tango.info ad 300x50
Usage outside tango.info
* no GIF in tango.info
The official file size 8kB is quite small, so you have to restrict what you want to bring into it. This small size helps tango.info that pages still load fast and additionally the image can also be used in future for mobile advertising, where bandwidth may be smaller.
Achieving small file size
- use one colour as background instead of complex picture
- JPG vs PNG
- JPG compresses photos better
- PNG compresses simple shapes / graphics better
- use a colour palette / indexed colours
- some programs have a function "use web colours only"
- black-white image:
- use png
- use grey-scale (instead of RGB)
