How to remove water marks from Web Gallery Wizard ??

Hey Friends

Please, any of you know how to remove the water marks from the thumbnail preview of the trial version of Web Gallery Wizard

Site http://www.webgallerywizard.com/Product/Index.htm

Thanks in advance

If the watermark is on the pictures is not that easy to clean away.
I should make the thumbnails using another program, or try another gallery wizard, there are many freeware on the Internet, just try google or big shareware sites like www.tucows.com

Thanks Roblam, I will look for other software
