This blog is written on Blogger, where multiple free blog websites are available to anyone with a Gmail account.
Unfortunately, Blogger doesn't have a built in tool for for making an embedded picture into a hyperlink. Instructions follow the break.
It requires tapping the "HTML" button at upper left while editing the blog. A picture HTML basically opens (in default mode) with href=[the picture] and src=[the picture]. You get into the HTML and replace the [the picture] following [href] with code like:
target="_blank" is HTML for "open in a new page."
