screenshots of login page to link out to actual login page

[ciresiemanym]

It seems as if it could be beneficial to be able to click on the screenshot of the login page and be taken to the login page. This would effect pages logging-in.md, requesting-access.md, and registering-your-study.md.

It appears it can be done in markdown but is best with a little HTML - I assume it would be similar to the image tags.

re:logging-in.md
it may seem redundant as there's a link to the login page directly above the screenshot of the login page - may be beneficial to include both?
