by your leave, but:

You talk about a jpg in the description but in the code is a path to a jpg, this would also match to the error message.

Just an idea...

Sorry, should be "in the code is a path to a
png" not "..to a jpg"

Do you see PNG in the list of supported formats in phpinfo() ?
Are you sure the use running PHP has access to the image?
