WWWForm.AddBinaryData  

function AddBinaryData (fieldName : String, contents : byte[], fileName : String = null, mimeType : String = null) : void

Description

Add binary data to the form.

Use this function to upload files and images to a web server application. Note that the data is read from the contents of byte array and not from a file. The fileName parameter is for telling the server what filename to use when saving the uploaded file.

If mimeType is not given and first 8 bytes of the data match PNG format header, then the data is sent with "image/png" mimetype. Otherwise it is sent with "application/octet-stream" mimetype.
