How to remove the image borders

Try adding the following code to the bottom of your theme’s style.css file:

.wp-caption {
    background: transparent;
    padding: 0;
}

Didn’t work ??
I appreaciate your help.

Can you post a link to your site?

Sure. Minecraftservers.biz look at the news images.

I went to the site but I don’t see any images with CSS borders around them. Can you describe what the “news images” are and where on the site they’re located?

For example the GodWorld logo. a gray border.

I ran your site through Adobe’s browser lab and the only browser I saw an issue with was Internet Explorer 6. Can you confirm that you’re using IE6? If so, the easiest fix is to update your browser.

If you have to support IE6 you can also look into adding a javascript fix like this one.

You can remove these borders in the advanced section of the visual editing mode. On the edit image screen choose “advanced” then enter 0 (zero) for the Border value…done.
Yes, it is manual, but I like being able to choose which ones keep the border (I actually like it around the block photos)…not around transparent bg images, though. Hope that helps.
