Hi Glenn,
In your CSS stylesheet, find:
#content-full img {
border: 1px solid #999999;
box-shadow: 0 0 5px 0 #777777;
The ‘box shadow’ property refers to the border you refer to. Change ‘5px’ to ‘0px’. You might like to remove the border by changing it to 0px too.
If you use the Chrome browser there is an easy way to figure out what you need to alter in the CSS. Right click on any element within the page (for example- your image with border) and click ‘Inspect Element’. This will bring up the element’s style properties where you can de-select/alter specific CSS rules (i.e ‘border=”0px”‘) and see live real-time results. Once you know what to change, you can get into WordPress and change it.
Hope this helps!
