You need to wait for the processing of the send() function to complete. Either by a timed wait, or receiving a notification from the receiver.

Why not move the processing task into a BackgroundWorker[^] thread?
You create the thread, show the image, and start the worker.
In the worker completed event, you hide the image.
That way your UI remains responsive, and the task is handled in the background.

The link includes an example.

Actually the send() returns something, can i receive the output using BackgroundWorker

Yes.
Set the DoWorkEventArgs.Result property in your DoWork handler, and retrieve it from the RunWorkerCompletedEventArgs.Result in the completed event handler. It's an object property, so you can return any type of value you want and cast it back when you want to use it in the RunWorkerCompleted handler.
