Amazingly enough it can. If you use the "-rrect" hint SiteGrinder will create the graphics and HTML required to create a highly efficient and flexible rounded rectangle on the final page.

The primary advantage of creating a rounded rectangle using this hint instead of just a standard graphical layer is that this type of element can be easily resized later in another tool like DreamWeaver.

It is also highly size efficient, especially if you use multiple rounded rects that are the same color, and hence will recycle the same corner graphics.

To use this functionality, just drag out a rounded rectangle layer using Photoshop's Rounded Rectangle tool and add "-rrect" to its name. SiteGrinder does the rest!
