These are the main types of graphics used on mobile phones:

• JPEG: The most widely used graphics format for mobile phones and digital cameras. It is excellent for realistic images (like photos) but does not support animation or transparency. Format: jpg, jpeg, jpe, jif.
• GIF: Nearly as popular as jpeg, best for small, detailed text or images with hard edges. Gif supports transparency as well as animation. Format: gif.
• Operator Logos: Operator logos are typically 72 x 14 pixels in size in a black and white image format developed by Nokia for the transfer of images to mobile phones. What makes this format unique is that it can be sent as an SMS and will be recognised by the phone (mostly Nokia phones, but also some Siemens models) as a graphic. All other graphic formats mentioned above can only be downloaded via WAP. For more info, see Nokia Specific and WAP Delivery. When you use 16ixty, the conversion process needed to transform a normal GIF or JPEG into an operator logo is carried out automatically.

It is quite easy to create your own graphics and almost all graphics programs support the creation of GIF and JPEG format files.

• Adobe Photoshop
• Macromedia Fireworks
• Paint Shop Pro

To create operator logos:

• Create a normal black and white GIF or JPEG image, 72 x 14 pixels in size.
• Upload via 16ixty as an Operator Logo.
• The operator logo will be created automatically and will be converted to the correct format.
