25C PDF Generation - Image File Height/Width Handling

Summary:

Has anyone successfully managed to apply styling to an image/signature file in the OOTB PDF Generation functionality? I'm not an HTML pro, but anything i have thought to try so far has failed and the image continues to display at it's full size. For example:

Coupled with:

<div class="image-container image">{{activity.x_attachment13}}</div>

Does not result in the image being contained to the widht of the container.

I'm sure it's possible and i'm missing something simple, but i cannot crack it at the moment.
