O$5.1.1 Loading image file to a variable using HTTPRead.

Has anyone an easier, more workable solution to retrieving an image from a website please?

I have the URL of the image as:
www.plastimo.com/media/catalog/product/e/c/eclate_pieces_detachees_enrouleur_1.jpg <www.plastimo.com/media/catalog/product/e/c/eclate_pieces_detachees_enrouleur_1.jpg>

and I want to be able to save the image on my local PC. I get so far, I can connect, get back both binary data and the full HTML text. But I was hoping with v8, there would be an easier way now. Would this oBrowser object be a saviour perhaps?

Thank you

Mike
