Level Design What do you use to convert images to 8 bit format?

What's used to create image previews? I have it resized to 512x256 already.

Any half decent image editing app (not mspaint) should be able to index images.

So does anyone know a specific program I can download. I can't find any that does this.

TheGimp should be able to do it.
Paint.NET too, I guess.

Both are free.

You can just use 24-bit bmps as well. Not ideal, but if it's just for the level preview...
Just make sure you set the LoD setting of the imported texture to Interface instead of World or else it will look horrible if people have their texture detail turned down. If it's set to interface it is always shown in Highest quality.

I use Adobe Photoshop CS.
Excellent piece of kit. Download the Nvidia DDS plugin tool, so you can create awesome Alpha textures
