It was an idea that was proposed by Jeremy Clarke about a year ago and soon, that idea will be turned into a reality. His idea was to fix the image caption system to allow links within the caption area of images. It’s an idea that I support as I’ve mentioned in a previous post as the image caption serves as the perfect opportunity to provide attribution and is especially useful for the Image Post Type.
Ticket #18311 which centers around this functionality has been blessed and looks like it will be added to WordPress 3.4 if all goes well. Everyone interested in this feature should follow the progress made on the ticket as well as test the patch and last but not least, provide feedback.
