Thank you for your replies, I'm looking forward for the definite answer.
As for the images, in order to decide which image to add to the column, I'm testing the value in the column and put in the image as a "state" image - Red/Green/Yellow.
The ExpressionInfo of the image is as follows:
=Switch(Fields!PrevGradeDiff.Value = -0.5 and Fields!PrevGradeDiff.Value 0.5, "Positive")
The image is not what makes the export fail, I've attached a modified example that does not use images and still doesn't export to excel. Maybe its the rectangle?
As for the work around:
unfortunately, when I do save the original report to rdlx, the images are not written to the file, and that breaks an important functionality of mine.
In any case, saving file into the file system in web application is pretty much a bad practice but as I've said before it won't fix my problems anyway...
