I'm using Bueno theme, and I've got it set so that a 3px black border appears around images in my posts. I set the max width for images to 864, but when I post images at 864 px wide now the black border doesn't appear around the right side of the image though it does appear around the other 3 sides. I have tried changing the max width to 867 to account for the 3 px border, and also tried changing the display width of images to 861 when I insert media but neither of those have fixed the problem.
Grateful for advice! Thank you.
The blog I need help with is photomadly.wordpress.com.
