Show title/url under clickable images & image border so users know it's clickable

As a user, I want to know when a blog image is clickable so that I know I can click the image to visit a link.

Currently, there is no way to tell when an image is clickable because there isn't a URL, link, or other "clickable" indicator.

Here is a sample blog with an image that is clickable but it's not clear because there is no link or title: https://steemit.com/dtube/@ura-soul/qqky6jwf#@ura-soul/re-cryptocowgirl-re-cryptocowgirl-re-ura-soul-re-cryptocowgirl-re-ura-soul-qqky6jwf-20171207t192751849z

The URL the image linked to: https://d.tube/#!/v/ura-soul/qqky6jwf
