Indexable File Types
The file type of the image is determined by the mime type and not by the file extension. This approach gives more exact results und how you name your files does not matter.
General
Common file extensions are given in the parentheses, but the files do not need to have these extensions, just the mime type counts. The list below is compiled from the document File types indexable by Google.
| File Type | Mime Types |
|---|---|
| Adobe Flash (.swf) | application/x-shockwave-flash |
| Adobe Portable Document Format (.pdf) | application/pdf |
| Adobe PostScript (.ps) | application/postscript |

Embedded Images
The file type of embedded images is currently not checked. Thus all file types are listed in the sitemap.
Linked Images
The list below is compiled from the document Supported image file types by Google. The Sitemap Generator additionally supports the TIFF format. As for all other indexable files applies that the mime type is the decisive factor, not the file extension.

| BMP | image/bmp image/x-windows-bmp |
| GIF | image/gif |
| JPEG | image/jpeg image/pjpeg |
