I have pictures in various sizes that I use as featured images for my blog posts. I have colored borders for every featured image, to help readers find specific content. Problem is, that featured image option will fit them so, that my picture/border sizes will be different from the original, where I have made them exactly the same.
Is there any way, to add custom borders, that stay constantly the same size, or to keep the pictures same as intended?
Thank you in advance!
