Transparent Sprites

How do I stop Game-Editor from making my sprites transparent.
I have some images made in paint-shop. They are saved as png files with no transparency.
However when I put them into GE it seems to remove the most common colour. For my game to work can't have any colour removal.

gE doesn't use the most common color. Since your images don't have an alpha channel, it takes the top left pixel and turns it transparent. To prevent this you can add one, or change the top left pixel to a color that isn't in your image (so only one pixel is removed).

Or, if you're working with pngs, simply add an alpha channel. :)

If it wasn't clear... that is one of the two solutions.

Sorry for the bump, but I'm having the exact opposite problem:
I want GE to remove the top left pixel (and the colors respectively), but it doesn't.
The image was saved with MS Paint (as .png) and as far as I know there's no alpha channel.
Size: 640x480 (tileset).

You are using windows 7, aren't you?
I've had that same problem.
It's problem with win7 paint, you need to save it as bmp.

Nope, vista. And it works with other pngs as well.
Same alpha color, same everything. Just not the measurements and frame counts.

I'm ready to bet that it saved it as 32-bit. Send me the PNG and I will check. If it is I can send you a 24-bit one

Yeah, this happened to NightOfHorror as well. I ended up running through all his animations with gimp and removing the alpha channels for him.

Thanks, it works now. Removing alpha channels certainly did the trick. Now I gotta worry about palettes and bit-by-bit file size reduction :3
