Hello, I'm working on a VBA add-in that generates and saves a series of WordML output documents in the background, but I'm having a lot of trouble with picture formats in the output. The output is undergoing some transformation in another system for web presentation, so my goal is to have the WordML binary enclosures as gif and jpg files. However, depending upon which workstation I'm at, I'm seeing jpg/gif, png, and/or wmz in the output. Some of the pngs have transparency, which of course looks wrong or completely black in IE. Is there any way I can control the binary format that the pictures are saved in via VBA?
