You want to merge a picture on top another? Or you want to extend an image?

[tunisiano32]

merge it on the top, with a fade in effect

So you want to cross-fade in the browser using Javascript or Flash? Or merge the two images using a graphics library like GD or ImageMagick?

I will try ImageMagick because i didn't try it
i was trying with GD and GD2+ without resulat

Can you post an example (one made in Photoshop)? We'll need to see the 2 starting images and the result you want.

Just to understand this, you want to:

- Have two images with alpha and "layer" them on top of each other. eg: making a "pixelized dress-up doll"

or

- Have two images, make them both transparent (50%) and overlay them on top of each other.

or

- Have two images and transition from one to another. I don't know if this is capable using GD by making an animated .gif but I think using javascript would be easier and faster.
