Hello.

Add logo stick to my airplane, make me mad.

Image

This 2 Google SAS Logo Images fit perfect in to my 747 body without any background color.
Image

I made my own logo El-Jet with Gimp.

One with white background and one with transparent background.

Image

(BUT) when I stick the images to my 747 the background turn black (Transparant) or white.



Can you guys tell me how to stick my logo without any background color.
Thank you.

Usually .gifs will export with a transparent background if you have made them that way but I have noticed recently they look black before opening them.
.jpg's will export transparent to white. They do not support transparency.
Exported .pngs support transparency.

Image
I took the green logo and just 'colour to alpha' it then exported it as a .png. After opening the picture of the 747 I added the logo as a layer, scaled it and merged but you probably know how to do that any how.
Then export as a .png to preserve the transparency.
