I hope I understand your question correctly. You want to show an image inside a cell, not a cell inside an image, right?

Please have a look at the CellPainterDecorator_Example that should include several examples how this can be done.

You do this the same way you do it in general in NatTable. Use labels per condition and register painters per label. If the images are quite static, that is the simplest way to do. If the images are dynamic based on some condition, you could also register a customized ImagePainter that identifies the image to render based on your dynamic condition or a label. We use this in NatTable internally for example in the SortIconImagePainter.

You need to get better in asking for help. How should anybody help you without seeing the code and even without explaining what is not working. With one vague sentence nobody can ever help you with your problems!

It seems you are missing some basic concepts in NatTable. Styling is done via labels and the ConfigRegistry. The method setCellPainter() you are showing is not a NatTable method, and IMHO it is wrong to have such a method and violates our concepts.

Please read some of our spare documentations to deal with your problem. I am not able to help here.
