LoadImage from web

Hi,

I try to load an image from my webserver, but my program hangs all the time. :-/

Local URL:String = "http://www.mywebsite.com/sprite.png"
Local Img:TImage = LoadImage(URL)
DrawImage Img,0,0

Img returns NULL, so the image is not loaded. If I locally load an image, it all works fine. Any ideas?

You need to use the prefix http::

Local URL:String = "http::www.mywebsite.com/sprite.png"
Local Img:TImage = LoadImage(URL)
DrawImage Img,0,0

you'll probalby want to make sure that it has loaded before you use if though, otherwise your app will just crash!

Note that some image formats can't be loaded directly, since the imageloader tries to seek in the stream... But you can get all of them work with one additional step:

Local pic:TImage=LoadImage(LoadBank("http::www.blitzbasic.com/img/brllogo-thin.png"))

That way the image is downloaded into a seekable memorybank first, before being passed on to the LoadImage function.
