RSS Feed random items (Please someone tell me if this can be done)

[Ellalex]

I guess I must have posted in the wrong forum some days ago for this so I will try here too. I thought it was simple what I am looking for but I guess is difficult since nobody knows.

 

I want to show photos of my products on other websites so I tried RSS Feed which worked good but I want to show random products and not the same products.

 

I use the below to use the feed for specific category but how to I randomize the products?

Please someone tell me if this can be done or not as showing the products in other website is necessary for me and want to know if I should keep on working with prestashop or find something else.

 

Thank you
