hi janak, thanks for your solution.
the pictures are not very big but in this case even small pictures slow down too much. for example the customer can browse through employees. then you are very insterested in the name for example but if the picture is loaded later it doesn't matter. the picture should only been shown when he is staying at a specific employee a while. number one is not feasible because the images come out of a database. number two i like more but the problem is fining a smart chunksize because it this case the size would depend on the speed of the net... so our solution we will implement in this case is a own servlet which is only for providing asynchronus pictures, we can load these directly on the client in an own thread... thanks for your investigations. regards Dejan mailto:[EMAIL PROTECTED] Wednesday, August 30, 2006, 7:30:46 AM, you wrote: JM> Hi Dejan, JM> How big is your image?
