Question regards to dynamically adjust blob field size.

Hi All,

I am having trouble to dynamically adjust the blob field. Right now, if the images I store in the database is smaller than the blob field size I inserted in the designer, there will be some blank space between the image and the border of the blob field. I wonder if I can adjust the bolb size dynamically with different image size so that there will be no blank space between the real image and the text objects follow the image. Thanks a lot.
