I was looking at the tulip bag but the straps do not go on the shoulder,but it says it comes with a strap. It does not say how long the strap is.
I think this page might answer your questions somewhat:
http://www.ebags.com/product/rioni/tulip-tote/131840
The Rioni site doesn't mention any magnets for that style, and I would guess it doesn't have them.
What I usually do when I want to find alternate pictures, is I go on google and search say:
rioni tulip
then go to images and look until I find something different than the stock pics.
And when you're looking for sites to buy from, go over to shopping on google. You won't find everything there, so another search on the main google might tease out a few more sites.
