The final destination of these images is the web. The annotation of these images is stored inside the image file itself. I use jpeg images and I annotate the images with <a href="http://jigsaw.w3.org/rdfpic/" target="_blank" rel="noopener noreferrer nofollow">RDFPic&nbsp; <svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"><use href="#fas-up-right-from-square"></use></svg></a> . RDFPic is a java application that stores metadate using the <a href="http://www.w3.org/TR/photo-rdf/" target="_blank" rel="noopener noreferrer nofollow">RDF (resource description framework) format&nbsp; <svg class="svg-inline--fa fas fa-up-right-from-square fa-2xs" fill="currentColor" aria-hidden="true" role="img" viewBox="0 0 512 512" overflow="visible"><use href="#fas-up-right-from-square"></use></svg></a> in the comment section of the jpeg file. Unfortunately the program can handle only jpeg images and not tif or png images.</p>
