Fixed image in CR 11

I'm using vb6 and CR 11. How to manage Image in CR? I inserted an image in the Report Header (ReportHeader Section1), then when I run it, the image size is not the same as during the design time. How it could be? I want a fixed size. The size of the image during design time must be the same as during run time. Do you have any solution to it? Thanks in advance : )

Is it bigger or smaller?

Hi

The original size of the image is 6 in. and reduced the size to 1.5 in. at the design time in vb it looks OK but at run time it is really small (I think more or less 1/4 in)
