The global default setting of the paintcompression can be different from 
the paintcompression of an image. An image has the paintcompression of 
the image format that it possessed when it was imported, i.e. fully 
imported (like with "put URL "binfile:filename" into img x), whereas a 
referenced image will have he default paintcompression setting.

This is probably what the docs want to state: "If the image was created 
with the import command, its paintcompression is set to the format of 
the imported picture file."

So you can have all he advantages of the PNG format, although the global 
paintcompression should be set to RLE.

However, the moment you change the imagedata of that image, the 
paintcompression will be the global one.

And, you can reset the global paintcompression any time you wish, for 
example via MSG.
