White 1px border around additionalImages

[discoduck]

Hi,

I'd like to know if it was possible to add a white border to every additional product image. Some of the additionalImages I have are focused horizontally and also vertically. For example: Horizontal ( 200x100 ) Vertical ( 100x200 ).

I have tried adding a border-style to the CSS corresponding to the additionalImages ID but it only adds a border around the field, and not the picture.

Is my request possible?

Thanks!

First matte all your pics to the same dimensions

What if this isn't possible due to image distortion? Are there any possible solutions?
