I have an image in my program which I want to superimpose against a background. However, the image will move around and I need the background image to remain in place while the front image moves. Furthermore, the front image has a dropshadow which I have created in photoshop.
In order to allow the front image to move around, have a dropshadow, and have the background image remain in place, I have set the background for the front image to be transparent.
I am "saving for web" now to PNG-24. However, Photoshop continually turns the transparent pixels either to be white or black - with no real alpha transparency. What should I do?
Here is the image itself:
And here is the image, superimposed over the background, in my program itself: (The key to notice is that in the top-right of the image, the drop shadow turns to white, overlaying and obscuring the background texture.)
What's the best way to solve this issue? I want it to look like this when all is said and done:
