This is our sample company logo. Make sure, this is a PNG with alpha transparency.

If required you can set categories and multilingual titels in the second tab.

After clicking "OK" the window for defining the image style will be opened.

Select "Create new picture layer" from the command menu

Select "Merge with target layer" to combine the logo file to the underling picture. The merging settings can be done later.

After that choose "Edit image layer"

Now, a new editing window is opened.

Select "Load picture file" from the command menu

Choose "..." right from the image file name and select you company logo.

WebImage ask you for copying the image file to your image style resource folder.
Choose "Yes" to continue.

Now we add a second command in the same window (right after the "Load picture file" command).

Therefore select "Draw border / glow" from the command menu

Play around with this command to get the right settings.

Guess to change the border width to prevent a clipping.

Now you can do some finetuning to this merging process, for instance set the size, position (+offset) and the fading mode.

In this sample we choose the "Soft light (for color)" fading mode to embed te logo in an unobtrusively way.
