Website Pictures

CJ asked 2 months ago

1) I am a jewelry designer/maker, redesigning my e-commerce website. Is it better to use stock photos of jewelry or photos of the jewelry offered for sale on my site?
2) Should the fullwidth header on each main page of the website be the same (for branding)? Or is that boring and likely to lead to a higher (lower? Whichever one you DON’T want… I forget which is which) bounce rate?
Sorry, I am new to website design…
Thanks for your feedback! CJ
