I was hoping for some help on ways to get an image(say a screen shot of google maps) from a URL and save it onto the hard disk.
Currently I'm able to :
1)Save the entire http code of a URL to disk(if I want to)
2)Save an image from "URls' that straightly lead to images" for ex: ( http://d335hnnegk3szv.cloudfront.net/wp-content/uploads/site s/501/2014/11/Balloons21.jpg )
Note: Using the below snippet will give you an idea of what i have achieved so far:

Url = ' http://chart.apis.google.com/chart?chs=200x100&cht=p& ;chd=t:10,20,30'
ourl = obj_new('IDLnetURL')
png = ourl->get(filename='E:\temp\gchart.png', url=url)
obj_destroy, ourl
im = read_png('gchart.png')
window, xsize=200, ysize=100
tv, im, true=1
