 The above code is fine, except there is an extra ) at the end. Another 
 option is to use the IMG helper:

 {{=IMG(_src='https://some_url/image01.jpg')}}

 If you are wondering why the above image in particular doesn't show up 
 when you attempt to display it with an img tag, they are probably using 
 some mechanism to prevent 
 hotlinkinghttp://simple.wikipedia.org/wiki/Hotlinking(e.g., they check the 
 HTTP_REFERER header and return a 302 not found error 
 when external sites attempt to load the image). If you want to display the 
 image (and doing so is not prohibited by copyright), you will have to 
 download the image and serve it yourself.

if I load they site by urllib2.urlopen(url)
 - how then load IMAGE to web2py DB?
