Our theme does not have such a plugin, perhaps you can find a plugin. We can suggest limiting the height of the wrapping block with CSS however it would just cut images, like this https://gyazo.com/386f16e94ae9b301a929b74d470f8128
If you accept it, here is the code:
body .blog-post-loop .post-img-wrapp {
max-height: 450px;
}
.
