Can we change image dimensions in payment field?

Is there a place in the code to change the dimensions of the image area in the product images area?  I am wanting to use a horizontal image but it seems to be constrained on width.

The product image size seems to be adjusted with injected CSS in your form.

If you need any further assistance on this, please provide us with more details.
