Dynamic image from dataset (blob)

system_migrated

Hi, I have problem with dynamic image in Birt. I set img on template report and set image data on dataset ->column (image) Date type blob.

In dataset when I get previous results I see my object name picture type String and "FFFFFF89 50 4E 47 D A 1A A...." in column Image (type blob) but in previews report i can't see my picture (I see only icon images).

Do you know what is wrong ?
