I find it easier to create visuals in PowerPoint than Adobe software. However, the image export functions in PowerPoint are not very sophisticated. It is hard to set resultion/DPI, choose format, set the exact image size, and/or control the naming of the exported files.
PPT ImageExport does all of this. The software creates an add-in in your ribbon. This is not a very sophisticated piece of software, but it has proven very useful for the design of my new company web site. A full license costs $30.
