Note that Twitter says:

What are the size and file type requirements?

Photos can be up to 5MB; animated GIFs can be up to 5MB on mobile, and up to 15MB on web. We accept GIF, JPEG, and PNG files. We DO NOT accept BMP, TIFF or other file formats. Your photo will be automatically scaled for display in your expanded Tweet and in your gallery.
