I don't have any pics, but I used silver pulls on the upper cabinets and plain white handles on all lower drawers on my white cabinets. It gives a more seamless look, to me.

why not just go to the houzz picture section and browse thru the 200,000 kitchen pics there rather than be limited to what gets sent to you?

it's really a question of what you like..and how you will be using them.
my old kitchen had the worst openings! those clip things that drove me mad! :) now i have handles on the lower ones and knobs on the top. if you are going to have drawers that close themselves? i prefer the handles because i can open them with one finger and close with a gentle hip push..
i have seen pictures of kitchens with drawer and cupboard hardware that i would constantly run into and be bruised (seriously:)) so it really depends on how you move around and access things while you are cooking.

I think a combination looks best. That's what I'm going to do in my new kitchen. Just find a line that works with your decor that offers all different types of pulls and knobs, in a finish that works with your home and other finishes in your kitchen. Good luck!
