You might find the video easier to understand if you look at the original posting athttp://support.genopro.com/FindPost10472.aspx
Basically the steps are:
1 Generate a Customised skin
2 Edit home.htm, changing
Report.WriteText
to
Report.Write. this will probably be about line 40 of a current file.
3 Add to the Document tab of the Report generator the following line.

You will have to type this line - you can not copy it as it has to be an image to appear on this forum.
Points to note:
If you are using a picture that is already in the report then it will be stored in the pictures directory, as shown.
If you want to use a completely different picture, which has not been used in the report, you need to get it onto the server. I found the easiest way is to put the image in the main program directory. This will be the images directory of your Customised Skin. GenoPro will then copy this file to the report, but change the location to 'images/mypicture.jpg'
Finally, remember that file names on the server are case sensitive, so if the filename is actually MyPicture.jpg, it will not appear on the GenoPro site, although it would be found on your PC as Windows is not bothered with such details
