I have an XML file that imports part information for a Parts catalog. The XML file is generated using VB and what not to create the parts info, and images into Indesign (CS). We are getting the XML to import just fine, and images come across ok, but are looking for a way to control the size of the images before the import comes across. Some images are big some are small, they are formatted in Photoshop that way.

What I need to know is; Can his be controlled with a XML DTD or Schema?
From cruising through the forums it looks like were going to need a script that does this.
Or can the XML control any of this? Either using an attribute or element tag?

I am lookinng into using a templates, but dont think this is the correct way to go, but i could be wrong. Any help would be appreciated.
