Hi Matt,
Thanks for your reply.
Your suggestion of using an image control that was saved as a link does work when viewing the transformed file within Internet Explorer.
By the way, I came across a way to view InfoPath forms with embedded Base64 images through Internet Explorer. If the form is exported as a Web Form the embedded Base64 images show up. The funny thing was that now the linked images no longer showed up. It basically did the opposite of the transformed InfoPath form, where the linked images show up but the embedded Base64 images didn't.
Turns out I will need to use this second method to work together with a browser based configuration management tool to access the forms through. But it is good to know that I can used linked images if I do use any transformed InfoPath forms again.
Actually, going back to the the transformation problem with the embedded Base64 images. During my investigation it seems that the transformation can not complete because the xsl file it is using can not find the function 'getImageUrl' that it needs. The function supposedly belongs to the 'xdImage' namespace or xmlns:xdImage="http://schemas.microsoft.com/office/infopath/2003/xslt/xImage ". It doesn't seem like they really exist, but maybe I am not understanding it properly. Do you know anything about that particular function or the xdImage namespace?
Thanks again for your help,
Kate
