Q: 

Is there an expectable function to find out what type an image is in C# using OpenXML?

I hooked into the question located at "Replace image in word doc using OpenXML". I noticed that there are several ImagePartType types. Is there any easy "built in" way to determine which type a specific image should be other than going by it's extension? The ImagePartType enum is also used in PowerPoint as is alot of the WordProcessingML structures.,

For instance, ImagePartType.Bmp on image1.bmp
ImagePartType.Emf on image1.emf
ImagePartType.Gif on image1.gif ImagePartType.Icon on image1.ico ImagePartType.Jpeg on image1.jpeg or image1.jpg ImagePartType.Pcx on image1.pcx
ImagePartType.Png on image1.png
ImagePartType.Tiff on image1.tiff or image1.tif
ImagePartType.Wmf on image1.wmf
