Is the section of code in your CSS that is controlling the border color of your images. Try changing the color to the same as the background or try deleting that part of the CSS out of the style sheet.
Jeffro, thanks, tried taking that line out, but the outline around the link & images (as well as every not-outlined link on the page) just turned the usual bright blue.
I can’t find one line in any file of this theme that pertains to links or images having a border or outline. Why would this happen to certain links? Can someone take a peek at this? The alt for these says “Direct link to file.” Why would these links be treated differently?
