save image from url to blob

Hello,

I would like to save jpg images from urls similar to the one below to a field defined as a blob, but I am not sure how to code it.

<img src="http://images.mywebsite.com/5f52f047f131d.jpg&quot; alt="image 15943-0" />

Is this how it should be coded if the url was extracted?

image_file = Image.new image_file.blob_image_field = open(http://images.mywebsite.com/ 5f52f047f131d.jpg) image_file.save

Thanks,

Frank
