PHP Doing Strange Things with URLs in Embedded HTML Tags

I generate some URLs at the beginning of each iteration of a for loop on an PHP/HTML page, like this: 

if ($chart_track->positionchange == 0) {
    $position_change_image = bloginfo('template_directory') . "/images/equal.png";
}
else if ($chart_track->positionchange > 0) {
    $position_change_image = bloginfo('template_directory') . "/images/up.png";
}
else {
    $position_change_image = bloginfo('template_directory') . "/images/down.png";
}

I then echo the $position_change_image into the src attribute of an img tag, like this: 

<img src="<?php echo $position_change_image; ?>" class="position-image">

This creates a broken link AND outputs the base of the URL (the template_directory part of it) in plain text. Upon inspecting the img src, it only has the final part i.e., /images/up.png. I try wrapping $position_change_image in an esc_url function, but that doesn't work either. When I echo the actual value of $position_change_image elsewhere, it's the full URL. Why in the name of God is it getting broken up and output like this?

Thats because you are calling echo twice because bloginfo echos automatically!

Instead use get_bloginfo.

Bloginfo Docs:

Displays information about your site, mostly gathered from the information you supply in your User Profile and General Settings WordPress Administration Screens. It can be used anywhere within a template file. This always prints a result to the browser. If you need the values for use in PHP, use get_bloginfo().
