size of war3mapPreview.tga??

in my map i have a preview picture thats 64 kb
later on when im importing icons and look, now the size of the war3mapPreview.tga has jumped to 192 kb

i dont know why it did that , only other thing that i did related to war3mapPreview.tga was open another map and look at its war3mapPreview.tga by extracting then looking at it with photoshop
(which was 192 kb)

not sure why it did that i exported the war3mapPreview.tga of my map out and looked at it and it was mine and also it is still 64 kb

now when i try to put it back itto my map, it says 192 kb again

whats going on?? it was fine at first staying at 64 kb
why did it change and how can i fix it?

Does the preview work ingame?

yea it works, worked b4 at 64 kb and is the same at 192

why did the size change?

hm.... i took out the picture then renamed it war3mapPreview2.tga
and its the correct size...

rename it back to war3mapPreview.tga then put it back in it says 192kb

then i open up the pic in photoshop and then save it as another 32 kb file
this file named war3mapPreview3.tga when imported is fine and is 32 kb
renaming the 32kb to war3mapPreview.tga again and try import it says 192 kb

why when i import the file name war3mapPreview.tga its 192 kb? it wasnt like that before

I'm justing guessing here, but WE may reserve that much space as a buffer for that screen. Mine is a clean 256, though.

When you convert it to tga and import it gets ALOT bigger. My Loading Screen was previously around 400 KB, and as a loading screen it was around 3 MB.

He is using a minimap, not loading screen.
