The Wolfram Language allows you not only to export graphics and sounds, but also to import them. With Import you can read graphics and sounds in a wide variety of formats, and bring them into the Wolfram Language as Wolfram Language expressions.
|Import["name.ext"]||import graphics from the file name.ext in a format deduced from the file name|
|Import["file","format"]||import graphics in the specified format|
|ImportString["string","format"]||import graphics from a string|
Import yields expressions with different structures depending on the type of data it reads. Typically you will need to know the structure if you want to manipulate the data that is returned.
|Image[data,opts]||resolution‐dependent bitmap images|
Structures of expressions returned by Import.
