If you are sending your photos by email, be sure they are not too large. 1MB per photo should be the maximum, 500 KB is better. If your photos are too large, they can take too long to download and your email could end up being deleted before your photos are reviewed.
Do not send your photos in a zip file and do not send a link to your personal website. No one wants a virus on their computer, so agents will probably not open the file or click the link.
