I couldn't find anything in Seller Central as to what the two types of variants mean of GLMR and EDTR. I saw that a few discussions had been opened about this, as well, but were locked. I searched AI and here is what I found:
In Amazon Seller Central, the Image Variant "GLMR" represents the "Glamour Shot" of a product. This type of image is typically used for marketing purposes rather than for detailed product listings.
What is a GLMR (Glamour Shot)? It is an enhanced or lifestyle-oriented image of the product. Often used in A+ Content, Storefronts, and external marketing materials. Usually features the product in an aesthetically pleasing setting rather than on a plain white background. Helps elevate the brand image and increase conversion rates by making the product look more appealing.
How to Use GLMR Images Effectively? Ensure High Quality – Use high-resolution images with professional lighting. Show the Product in Action – Feature the product being used in real-life situations. Align with Brand Aesthetic – Maintain consistent colors, themes, and moods that match your brand. Use in Marketing Campaigns – Include in Amazon A+ Content, Sponsored Brand Ads, and social media promotions.
What is an EDTR (Editor) Image? This image variant is typically used for secondary product images. It may include graphic overlays, callouts, or text descriptions to highlight key features. Often used in A+ Content, product detail pages, or enhanced brand content. Helps to visually explain product benefits, dimensions, or usage instructions.
How to Use EDTR Images Effectively? Add Informative Callouts – Highlight key product features such as materials, durability, or special functions. Show Dimensions – Include size comparisons or measurements to give customers a clear understanding of the product. Explain Benefits – Use text overlays to emphasize how the product solves a problem or enhances the buyer's experience. Maintain Amazon Compliance – Avoid promotional language like “#1 Best Seller” or unnecessary logos that could violate Amazon’s image policies.
