Image Formats

There are many image file formats in the world. However, the ones listed below are generally recognized as usable on the Web, though BMP is generally not recommended as browser support is potentially constrained; it should usually be avoided for web content.

While it is not especially important that a web crawler can support image formats, the examples below are provided for completeness. Note that as not all browsers support all common formats, some images may not display below.
