What is the risk?

When I decided I wanted to add a visitor counter to my website, I scoured the Internet for a ready-made solution. I don't yet have the expertise to write my own routine, so I was hoping to find something relatively simple to implement. I encountered numerous sites offering free counters. On most of them, the process was the same. They provided a mechanism for customizing the way the counter should look. After selecting the styling options and viewing a preview, you push a button to generate the corresponding HTML code. The code generated is an HTML <img> tag which is to be placed in your HTML document. Typically, the <img> tag is wrapped in an anchor (<a>) tag.

From what I've been able to ascertain, behind the scenes there's some kind of CGI process. I'm not sure exactly how it works, but my best guess is that every time my site is loaded, the server increments the count and sends me a new picture. Anyway…

From among the myriad choices I had, I elected to use a site called cutercounter.com. The landing page looks like this:

After selecting a style that I liked, I entered the URL of my website into the "Your Website URL:" field and clicked on the "Get Your Counter HTML Code" button. Thereafter, the following screen was displayed:

I placed the code into my HTML document, which yielded the following:

I'm happy with the result, but I have a concern. I'm wondering whether there's a risk in placing that unsecured (http versus https) link in my document. I don't have sufficient expertise to make that determination. Do I have cause for concern?
