Is it allowed to have links in the description of a photo?
Could either be links to general articles describing the place (e.g. from wikipedia) or to the official site of the place, which may be commercial in nature (for instance a museum with a ticket fee, a Hotel, etc.).
The links are not going to be directly clickable anyway (for security reasons URLs are disabled) but users may copy / paste the address in their browser bar.
