Dear monks

It is easy to display an image into a Tk widget, for instance, a Label or a Text widget. All examples I have seen refer to image files stored locally. I want to show images available on a server for which I have a URL. Is there an alternative to downloading the file image locally and then show it in Tk? A little bit like a Browser (which I think does not save all images locally to display them).

If there is no alternative than downloading the file locally, I try to to write the image to a temporary file:

use LWP::Simple;
use File::Temp;
my $tempFile = new File::Temp( UNLINK => 0, SUFFIX => '.jpg' );
#my $tempFile = 'img.jpg';
my $url='https://upload.wikimedia.org/wikipedia/commons/thumb/c/cd/Win
+d_turbines_in_southern_California_2016.jpg/200px-Wind_turbines_in_sou
+thern_California_2016.jpg'

getstore($url, $tempFile);

[download]

Unfortunately my file is empty, and I do not get any error message! If I write it to an ordinary directory, however, I can download the file fine. Any idea?
