Which image format should I choose for my grid?

There are 3 popular formats used in the www: PNG, JPG (JPEG), GIF

PNG (Portable Network Graphics) is a losslessly compressed image format. PNG was created to both improve upon and replace the GIF format with an image file format that does not require a patent license to use.

JPEG (Joint Photographic Experts Group) is a commonly used standard method of lossy compression for photographic images. The file format which employs this compression is commonly also called JPEG; the most common file extensions for this format are .jpeg, .jfif, .jpg, .JPG, or .JPE although .jpg is the most common on all platforms. JPEG is the most common format used for storing and transmitting photographs on the www. It is not as well suited for line drawings and other textual or iconic graphics because its compression method performs badly on these types of images.

GIF (Graphics Interchange Format) is a bitmap image format for pictures with up to 256 distinct colours. A GIF file employs lossless data compression so that the file size of an image may be reduced without degrading the visual quality, provided the image fits into 256 colours. The GIF format's 256-colour limitation makes it unsuitable for photographs, though losslessly compressed photographs tend to be unacceptably large for the web anyway. Therefore GIF is normally used for diagrams, buttons, etc., that have a small number of colours, while the JPEG format is used for photographs.
