Someone is using my photos on Walmart
A Walmart listing is using your Etsy photos. Do these three things before you pay anyone who emails you offering to handle it.
Save the page. Copy the link, take screenshots, and write down the date. Your original Etsy listing, and the files you uploaded, are the proof the photos are yours.
Report it on Walmart's own form. You have to be the rights holder or someone they authorized. You do not need a Walmart seller account. The public form is brandportal.walmart.com/ipservices. Choose Copyright, add the listing links, and point at your original Etsy listing. Temu, SHEIN, Amazon, eBay, AliExpress, and other Etsy shops have their own forms. Use those, not a random email.
If Etsy removed your listing because the copy showed up first, write Etsy and show them your original files and the date you published.
If it was Temu, start here. If it was SHEIN, start here. If it was Amazon, start here. If it was eBay, start here. If it was AliExpress, start here. If it was another Etsy shop, start here. If it was TikTok Shop, start here. If it was a Shopify store, start here. If it was DHgate, start here. If it was Pinterest, start here. If it was Redbubble, start here. If it was Society6, start here. Want to see if one listing's main photo turns up somewhere else? Check it free. No account.
