Place watermark image on other images (C#, ASP.Net)

Question

How do I add a watermark image onto other images?

I\'m able to place text on an image as a water mark but now I have an image that I\'d like to put on there instead

Answer 1

in the same place where you call gr.DrawString, you can also do gr.DrawImage(position, size, overlayImage). It helps if your image-to-overlay is loaded from a PNG file (with transparency) to produce the best quality.

Answer 2

Here is another solution which uses GDI+
