How can I combine multiple GIFs into one GIF file? I just want to display the images side by side.
Given this question is asked on SO, I'm going to go with: GdiPlus exposes an API on Windows you can use to read, and write GIF files (amongst other file formats). You will be able to combine an arbitrary number of source images into an animated gif.
You can check out some of the CSS Sprite generators out there. These are designed to combine multiple image files into a single file to reduce the number of connections needed to load a website.
If you have Photoshop you can combine multiple Gifs into 1 file pretty easily. Take a look on Youtube
