inserting images with different url's

hi,
great tool.
i have a (possible small) problem with inserting images into the grid. i get my data for the grid from an oracle database. for every record there is a field with a different image-url like 'http://localhost:8081/test/images/companylogo.gif'.
how can i insert this image (like an <img src=''>) tag to the grid ?

thanks for your help.
