YOu need to go to the folder and give permissions to the folder.

Sorry, but the guess at the cause of the error is not correct. The real reason for the error is that imread() cannot take wildcard file patterns as an input string. You need to give the name of just one file - no * asterisk.

If you need to read multiple files, especially ones in subfolders, see imageDataStore().
