File type of the specified item of the upload list.
value = getImageUploader("ImageUploaderID").getUploadFileType(Index);
A positive integer which specifies an index of the upload list item (i.e. the upload file). An index is 1-based. In other words valid value is in range [1, UploadFileCount].
A string value that returns a file type of the specified upload list item.
Do not confuse this property with UploadFileFormat. The file type returned by this property is retrieved from system (determined via the file extension). This is the same string which is displayed in the Type column of the
Details view. In the same time, file format is determined with Image Uploader by analyzing file content (rather than the file extension).
