"""
This script imports images and creates Planes with them as textures.
At the moment the naming for objects, materials, textures and meshes
is derived from the imagename.
One can either import a single image, or all images in one directory.
When imporing a directory one can either check the checkbox or leave
the filename empty.
As a bonus one can choose to import images of only one type.
Atm this is the list of possible extensions:
extList =
('jpeg', 'jpg', 'png', 'tga', 'tiff', 'tif', 'exr',
'hdr', 'avi', 'mov', 'mp4', 'ogg', 'bmp', 'cin', 'dpx', 'psd')
If someone knows a better way of telling if a file is an image which
Blender can read, please tell so ;)
when importing images that are allready referenced they are not
reimported but the old ones reused as not to clutter the materials,
textures and image lists.
Instead the plane gets linked against an existing material.
If one reimports images but chooses different material/texture mapping
new materials are created.
So one doesn't has to go through everything if one decides differently
after importing 236 images.
It also has an option to translate pixeldimensions into Blenderunits.
