  1. What's the preferred way of reading information (width, etc.) from an image file. While working on the QT side should I rely on QT tools (i.e. QPixmap and the like) or should I try to use something else?
  2. Although they currently don't, the supported image formats should vary according to what's linked in TeXmacs, right? What's providing basic image support? How can I get a list of what's supported?

In the Qt version we try to rely as much as possible on the library's support. In the port you can rely on its image manipulation functions. Ideally no other libraries should be linked if it duplicates some functionality available in qt. The main constraint is Windows where less libraries we need, the better. 

For the moment the main limit is ps and pdf import since Qt is not able to read ps,pdf. At some point we should think to add Poppler support (which has a Qt bridge).
On the Mac we can rely on Cocoa for Ps/pdf support (if macosx-extensions are enabled)
