You saved an Project with an Image, than when its open you delete the image.

After this all the settings of the project are on default........ so when you want to use the same shader on an other image you need to open the other image first and THAN delete the first one or the settings are default again.

Hi, it works fine on my side, or I didn't understand well : 

But I'm agree should be better to be able to replace the image for example to keep the animations. I will do that certainly for next release.

ok thx

Hey, in 0.6 you can now replace images.
