Explanation
Correct code block:
spark.read.format("binaryFile").option("recursiveFileLookup", "*.png").load(path) Spark can deal with binary files, like images. Using the binaryFile format specification in the SparkSession's read API is the way to read in those files. Remember that, to access the read API, you need to start the command with spark.read. The pathGlobFilter option is a great way to filter files by name (and ending). Finally, the path can be specified using the load operator - the open operator shown in one of the answers does not exist.
