Combine two images

Hi people,

What is the best way to combine two images. i want to combine the 2 images and then use as a texture.
For example if i want to combine this two images + and get this result .

Thanks in advance for any advice.

If there is alpha on the images, you can use an fbo and draw one image on top of the other inside the fbo and then use the textureReference in the fbo.
Or if there is no alpha you can use a glblendfunc similar to multiply in photoshop to remove the white

Thanks Nick, thats work like a charm.
