Apache Commons Sanselan has support for reading and writing BMP, JPEG/JFIF, TIFF, GIF and PNG from your list.

Apache PDFBox can convert PDF files to images (see PDFToImage code).

Apache POI can read doc, docx, xls and xlsx, but I am not aware of an easy way to convert them to an image (if that is what you would want to do). What you could probably do is make a conversion to a PDF first and then from PDF to an image.
