On a marketplace, images are doing the job a shop assistant would do. A shopper who cannot tell the size, the contents or the finish of a product from the photographs will not buy it, however good the copy is. The rules about image formats and dimensions are set by the platform and are updated, so the sensible approach is to build a good set and check it against the current documentation before you upload.
Understand what the main image has to do
The main image is what appears in search results and it carries the most weight, which is why its rules are the strictest. It generally needs to show only the product being sold, on a plain background of the required colour, correctly proportioned with nothing cropped, at a resolution that stays clear. No text overlays, no promotional badges, no watermarks, no accessories or props unless they are actually included in the box. Many sellers lose a listing's impression to a main image that is technically acceptable but weak, so treat the rules as a starting point rather than the goal.
Build a set that answers the buyer's questions
After the main image, use the remaining slots to remove uncertainty. Show the product from the angles a customer would want to see, close up on the details and any labels, include a hand or a familiar object for scale, lay out everything included in the box, show the packaging as it arrives, and photograph how the product is used or cared for. If the item has a size, a fit or a compatibility, show it. This is where most listings are thin, and filling these slots usually matters more than any change to the copy.
Keep consistency across the catalogue
Use the same background, lighting direction, angle and framing for every product in the range. A consistent grid looks considered and makes a shopper more willing to browse. Check that colours in the image match the product under normal light, since a customer receiving a different shade is a return and a poor review.
Watch what you cannot photograph
Some products are difficult to shoot well: transparent items, highly reflective surfaces, very dark fabrics, soft goods where shape reads as volume rather than size, and anything whose scale is genuinely hard to convey. For these, consider a rendered image or a composite that shows the product accurately, with any alteration limited to presentation rather than substance. Never alter a colour, a dimension or a finish to make the product look better, since a mismatch between the image and the item is a misleading description.
Prepare the images before you upload
Rename and export files systematically with the product identifier and the shot type, so a rejection can be traced to a specific frame. Export at the technical specifications the platform currently accepts and the category allows, and keep the originals. Resizing down from a large master file is reliable; enlarging a small file always looks worse, which is why the source image matters more than the export settings.
Check the rules before you upload
Image specifications vary by category and are revised over time. Before a bulk upload, read the current image guidelines in the official seller documentation for the category you are listing in, including the accepted formats, minimum dimensions, aspect ratio and any background rule for the main image. If the platform rejects an image, read the reason in the notice rather than guessing, and check whether a watermark or editing tool is adding something the platform does not permit.
Get a second pair of eyes
Show a finished set to someone who does not know the product and ask them what the product is and how big it is. If they cannot answer from the images alone, the set is missing frames. Review the images on a large screen and on a phone, since most customers never see them at desktop size.
Common reasons a listing gets penalised
A main image that includes text, a badge or a prop which is not part of the box. A product shown with a competitor's packaging visible in the background. Two listings sharing the identical image file, which can make the platform treat one as a duplicate. Images lifted from a manufacturer's material pack without checking the licence. And descriptions claiming a feature no image or specification supports. None of these are tricks worth taking; each is a genuine risk to the account as well as to the product.
What to ask an image service
Ask what the fee includes: how many products, how many frames each, retouching, resizing, delivery time and usage rights. Ask to see a complete set for a comparable product rather than a selection. Ask what happens if a frame is rejected after delivery, and how the images will be handed over so you are not dependent on one person keeping the originals.
Our marketplace guides cover the other listing fields. If you want images briefed, listed and checked across a catalogue, our Amazon and Flipkart listing work starts at INR 1,500 per product, with marketplace commissions, platform subscription fees, shipping and ad spend separate and set by the platforms. You can send us your current images and we will tell you honestly which frames are missing.
Common questions
What size should Amazon product images be?
Large enough to stay sharp when a customer zooms in, and prepared at the technical specifications the platform currently accepts for that category. The required minimum dimensions, aspect ratios and formats are set by the platform and are updated, so read the current image guidelines in the official seller documentation rather than a remembered figure. Undersized images are one of the most common causes of a weak impression in search.
Why was my image rejected?
Common reasons include a main image that shows extra items, text, logos or watermarks, a background that is not the required plain colour, incorrect proportions with part of the product cropped, insufficient resolution, or an image that does not show the actual product being sold. Check the rejection notice for the specific reason, and look at the current category rules before resubmitting, since requirements differ between categories.
Do I need professional images to sell well?
Not necessarily. For a simple product, good light, a plain background and consistent framing will produce usable images at low cost. Professional or product-rendered images help where the item is small, reflective, transparent, delicate, or where the visual presentation is the main reason to choose you. Whichever route you take, the set still needs to answer the practical questions a buyer asks.
