I noticed that you wanted to apply the code of Sale banner on your catalog images.
I would suggest a foolproof method of adding badges or labels on catalog images as this will quickly grab customers' attention, and trigger factors such as urgency/social proof which can nudge them to purchase.
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.
We're offering 10 free product stickers for every new install! Try out, and witness the boost of conversions in your store.
Hope this helps.
