Import image script

I’m trying to find the function to import an image, I can only find import sound and import movie. I’m trying to import PNG files, but information on importing psd files as layers would also be useful to get a better understanding of what’s going on.

I am also looking for a js script call to import images. So far in the documentation I cannot find it under files, nodes, create, or any other conceivable class. The existing scripts call on other .js or .py files that are indecipherable to me. Is there a function in scripting to import an image?

Did you find any information about it?
How get import action algorithm (image and movie) for rewriting directory path and finding there .movfile and finding all image automatically?
