Hover image flashes a different colour border-how?[FIXED]

[M33R4]

Are there any instructions out there on how my image can change border colour when the user hovers over the image please? I have 2 images I can use: one full image and another with just a different border colour.

Thanks.

Use the :hover selector in CSS to apply styles - see https://developer.mozilla.org/en-US/docs/Web/CSS/:hover
