The problem is caused by creating a directory with the name of the image, then trying to write a file in place of the directory. In other words, you are first creating a directory named:
Documents/girl.png/
then you try to write a file to the path:
Documents/girl.png
Yeah I saw that but since all I do to grab a pic from the net is hold down my finger till the menu pops up and I choose save the pic then how am I possibly doing that at all? I am not doing any ‘creating of a file path’ that I know of.
