How to change map preview?

I know this sounds really nooby, but if I import my picture and change the naame to "war3mappreview.tga" (without " ") a white preview appears.

Why?
I don't know ?
I hope you can help me.

Thx.

Imported previews must have the following specs:

- .tga format
- 128x128 or 256x256 Dimensions
- Saved in 32-bit format

Save the file like that (i use photoshop for it myself) then import it and rename it to war3mappreview.tga and it should work.

Its like Angelusz sed, if u dont understand read it!!

The first time I used costum minimap preview I got error messages when I tried to play the map. I was able to solve that by right after I imported the image, save the map with another name so you have a backup. Then close the map in the editor and then open it again. Don't test the map just after imprting the image. Save and close first. Otherwise you might get errors like I did.

Thx.

I'll test it in a few hours.
