Image editor closes when I open it.

[Volcan]

I use AGS 3.2.1

The image editor closes once it opened.

I can't use it.

Do you mean you are trying to open sprites in external editor by double clicking on them?
Have you set the path to your graphics editor's executable in AGS Preferences ( File -> Preferences -> Sprite editor ) ?
If yes, what exactly program is that?

[Volcan]

AGS editor is set by default: paint program registered with windows.

Any better Image editors would work with AGS editor?

What operating system do you have?

I just checked this in Windows 7 and it looks like AGS really can't start a "default associated" program. Don't know why (maybe it does not make it in a way compatible with Win7).
But you can put in a path to any graphic editor you have on your computer (that support editing BMP and PNG formats).
For example, MS Paint:
c:\windows\system32\mspaint.exe

I have Vista. I guess it wasn't work either.

Nevermind. iDraw works fine.

When I click on the picture, i was expecting editing transparent color, not the whole picture.

I imported a gif image with many frames. When executing, the background image became black and I want to change another color transparent.

In AGS 3.2.1, there is no option for transparancy option when importing images.
