Including complex multimedia objects as part of an electronic thesis or dissertation is a possibility. You are encouraged to work with your committee to gain their approval and assistance. Be sure you understand the implications of including multimedia in your thesis or dissertation before making that commitment.
It is important to remember that your thesis or dissertation will be archived for the foreseeable future. Technology changes at a rapid pace, and file formats fall out of favor. When that happens, new technology may not be able to make use of very specialized files when they become obsolete.
Attaching vs. Embedding
Most images can be embedded within your document as part of the PDF. However, extremely large images with a high resolution may cause your document to be difficult to upload to TRACE, because of the sheer file size of the resulting document. Files such as JPG, PNG or GIF images at a moderate size should do just fine. File formats such as TIFF provide very high resolution and detail at a cost of file size.
For very large high-resolution images, such as maps or satellite images, and for all other types of multimedia files (audio, video, etc.), you are encouraged to attach the files as supplemental files to your main document.
