How to get the Flickr photos URLs starting with HTTPS?

The quick fix that I implemented and that you may like to eventually adopt is:

1) replaced:

$link = esc_url( $photo->link );
$src = esc_url( $photo->media->m );
$title = esc_attr( $photo->title );

2) with:

$link = esc_url( $photo->link );
$httpslink = str_replace("http:","https:",$link);
$link = $httpslink;
$src = esc_url( $photo->media->m );
$httpssrc = str_replace("http:","https:",$src);
$src = $httpssrc;
$title = esc_attr( $photo->title );

Another thing that I did for the sake of sticking to HTTPS (not really necessary for my request) was to replace the 2 instances of “http” with “https” on the flickr api URLs from the plugin file.

Thanks,
