[Closed] How to load Vray Material Bitmap

I was reading about Vray Material Library script, it is good work
I want to ask if we modify this script to load Material with Bitmap on internet, so, what do we do
below is my script section

	   on btn_One pressed do
	(
		bt = BitmapTexture()
		bt.filename = "http://www.illusion3d02.com/TEXTURES/4.jpg"
		meditMaterials[activeMeditSlot] = VrayMtl ()		
		meditMaterials[activeMeditSlot].name = "First Texture"
		meditMaterials[activeMeditSlot].texmap_diffuse = bt		
		meditMaterials[activeMeditSlot].reflection_lockGlossiness = off
		meditMaterials[activeMeditSlot].hilight_glossiness = 0.99
		meditMaterials[activeMeditSlot].reflection_glossiness = 0.91
		meditMaterials[activeMeditSlot].reflection_subdivs = 30
		meditMaterials[activeMeditSlot].reflection_fresnel = on
		meditMaterials[activeMeditSlot].reflection_lockIOR = off
		meditMaterials[activeMeditSlot].reflection_ior = 1.7
		meditMaterials[activeMeditSlot].reflection_maxDepth = 10		
		meditMaterials[activeMeditSlot].refraction_glossiness = 1.0
		meditMaterials[activeMeditSlot].refraction_subdivs = 5
		meditMaterials[activeMeditSlot].refraction_ior = 1.486
		meditMaterials[activeMeditSlot].refraction_maxDepth = 5
		meditMaterials[activeMeditSlot].brdf_type = 0
		if $ != undefined then $.material = meditMaterials[activeMeditSlot] 
	
	)  

but it is not working with internet path
