For years, I've inserted images into text pages in Dreamweaver and set their borders into a box in the Properties tab that allowed me to enter a number that created a border with that number's pixels on all sides of the inserted object, but that box is missing in my CS6, and I can't figure out where to enter image border settings in the new version and would appreciate anyone's insights. Thanks!
Its all done via css now.
You would create a 'class' in the css panel with the desired border you need then attach the class to the image:
<img src="myimage.jpg" width="250" height="250" alt="" class="imgBorder" />
In addition to osgood's suggestion, if you want all images to have the same border, just create a style rule for the <img> tag:
border: 5px solid black;
That automatically puts a 5px black border on every image.
