I am trying to scrape some data from this website and grab the high resolution image behind the 'Download' button. In my firefox ESR browser when I click the download button it opens the image in the same window, however when I save the data I get "data:image/gif;base64,R0lGODlhBwAFAPUAAEJBN1VXSFlWSV9aS2djUnBvWXxzXHJ3ZoJ/aoaCaJGAZYeLdY2Lco+Pd5GNdpuUeJWYf6WVeJOWgJ6cgZediKypj7Gyl7qyk7KymLa3nr68n7++oby9o8G9oMLAoMDAo8zGp9DFpNrTsAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAACH5BAAAAAAALAAAAAAHAAUAAAYhwAxn0/lgKiGQRSNyCC6SBcWDAEwOAUiDMHgkCgyDIhIEADs=
"
for the image data. Any help correctly downloading the image or downloading it from the download button appreciated!
