Here are some door and window textures that I´ve made sometimes.
I´ve digged them out for our current project.
I think they might be useful ?!
They are based on photos from Mayang´s Free Texture Library -->

So they are free for commercial use.
All textures are in .pcx format.

very nice contribution. My favourite is the green door

Thanks.

You might cut the green one a bit on the right side, because there´s
a part of the frame still visible

i was wondering how you fit the texture onto a door? i want it to fit perfectly to my rectangle block that is supposed to be the door.

That´s easy. When you apply the texture within the the proberty window,
you can hit the "F - Button". This way the texture will be perfectly fit with your block:

ohh ok thanks alot!
