One of the most common customizations is to place your corporate or department logo on the Knowledge Center home page.
To replace the graphic:
Create the new graphic and save it in a GIF, PNG or JPEG format. The graphic should be close in size to the one provided with the software and be named small_logo.gif (or .png, .jpg, etc.).
Move the provided small_logo.gif file from <install directory>\Web Sever\KCenter\Images to some location outside of the Knowledge Center installation directory in case you should need to restore the original logo.
Copy your custom logo image named small_logo.gif to the <install directory>\Web Sever\KCenter\Images directory. Note that this directory is overwritten during Knowledge Center updates, so you should store the original of your custom logo in a directory outside of the installation location.
Run the imagegen utility to rebuild the images.xml file. This utility can be found in the <install directory>\Web Server\KData\bin directory.
Double-click on ImageGen.exe.
Browse to the images directory, <install directory>\Web Sever\KCenter\Images and click Open.
Click Create Images xml. A message tells you how many image files were converted.
Note: The imagegen utility may also be run without the GUI interface if the path to the images directory is specified on the command line. This allows you to create a batch file to replace the logo, since the images directory is overwritten by Knowledge Center updates.
