You can use this image everywhere, even on you collection page. Feel free to use this one for free if you like it.
I noticed that you wanted to apply sold out badges on your catalog images.
We have developed an app (Modemagic) that will help you add product stickers/badges on your catalog within seconds. And we have an extensive collection of customized stickers based on different occasions (Sale & Discounts, Pre-Order, Trust Badges and much more) You can also create custom badges based on what copy you prefer.
No complex edits, no back & forth with designers. Update your store within seconds!
Don’t find a sticker that meets your need, reach out to us on chat for a custom design. We also create stickers in various languages. Check out this app on Shopify here.
Hope this helps
