Blending images using paint shop pro

I have 2 bmp images that I want to blend together without any white area around them. How can I do that using Paint Shop Pro?
Thanks in advanced

Try this:
•Create a new canvas with a larger size so that you have room to move around
•Open your two images.
•Select, copy and paste the image as a new layer on the canvas one by one.
•move the images around until you have them as you want them to be or as close as you want. And then Save as image1 without any merging.
If there is an overlap in your image, feather it in the layer to help it blend. You can also adjust the layer blend as required, then merge the layers and use either the clone brush or the touch up brush
