Problems with vertical alignment of images in Safari

Hi!

I’ve got a web showing mainly images. The template is called “Polaroids” but it’s old and no support is given. Here’s the web: https://gabrieldiazamunarriz.com/

The problem is the following: Safari is showing a wrong alignment when the image caption has 2 text lines as you can see in the picture:

However, this does not happen in Chrome, Firefox nor IE as you can see in the following pic:

Any ideas?? I guess it should be something in the style.css regarding the vertical-alignment property of the image or title, but I haven’t found it…
