How to load an image from an URL and create a GUI texture from it:local imgurl = "http://www.site.com/image.png"
http.request(imgurl, "GET", function(self, id, response)
local img = image.load(response.response)

EXAMPLES
Load an image from an URL as a buffer and create a texture resource from it:local imgurl = "http://www.site.com/image.png"
http.request(imgurl, "GET", function(self, id, response)
