Which file extensions indicate only graphics files?

BMP and GIFis the answer to this question. DOC cannot be the answer because DOC file stands for documents which may have been saved in Microsoft Word or any other word processing app. TXT cannot be the answer because even if JPEG signifies a media file, TXT refers to items that are saved through Notepad. GIF is usually a favorite of people who like moving image files that are not on video format. BMP is also a type of media file that signifies that it may be an image.
