It's vertically integrated to be social. As such, the following are not considered important: > Original photo size (additionally, optional sizes) > EXIF data > Compression > Sharing as a link, embed, BBCode, etc. -- anything outside of Facebook can be done by copying image URL, but that URL can change without a moment's notice.
