bmp images showing backgrounds

Hi,

We have an odd problem, we have various reports with *.bmp and *.jpg images on them. They have no or clear backgrounds.

When we run the report in the designer, the images look fine. When we run them through our dll that uses the API these images look like they have a faint grey background on them.

We have checked that the printer drivers look up to date.
