Help on Long resource intensive operation with images

I need to combine image files and show progress dialog in a windows based application. I do not want to block the existing windows application and should be able to do other operations with it.

Please help with an approch. I have heard of worker thread and UI thread but which to use at what time to solve this issue would be helpful

A simple solution is to periodically call Application.DoEvents() inside the image processing loop which will keep the user interface responsive

Alternatively you can use background worker thread
