I had almost the same problem as you with the reports, and I couldn't find any god way to solve the problem inside LV. My solution is to use ActiveX to export the data to Excel or Word. The ActiveX interface in LV is simple to use and there are some examples at the NI homepage how to use it. I also create the graphs directly inside Excel instead of exporting them as a picture from LW.
One other problem that I dint manage to solve is how to get a decent picture file out of a graph in LV. You are writing about the gif and png format but none of these is relay god if you want to include the picture in a document. Both those formats are pixel built up and I would like to have a vector image like the wmf format instead. The vector format is scal able and has a bit better quality. If you right click on a graph and select copy then paste it into for example Word, you get some kind of object that is scalable and nice locking but I newer figured out a way to do this by code. Maybe someone else in the n.g. knows some thing about this.
