Product page images: the ones that block you and the ones that sell

Product images do two jobs almost nobody separates: convincing a person and passing a channel's checks. They are different jobs with different rules, and the perfect photo for the first is often the one that gets the product rejected by the second.

The four things that get a product rejected

Promotional overlays. The "-30%" badge, the "New" ribbon, the frame with your logo. Ad channels do not allow them, and almost nobody added them on purpose: they come from the theme or from an app that stamps them on afterwards, so the photo is clean in the back office and not online.

The placeholder. The "photo coming soon" image uploaded months ago and never replaced. It does not only get rejected: it tells whoever arrives that nobody is looking after that product.

The product too small in frame. A beautiful lifestyle shot where the object occupies an eighth of the space works on Instagram and gets discarded as a main image, because you cannot tell what is being sold.

The collage. Several views in one image, or text listing features inside the photo. Convenient for a human, non-compliant for a channel, and unreadable for an engine.

The first image has one rule

It has to make clear what the object is in a tenth of a second, on a screen the size of a stamp, among twenty others.

Which means: product large in frame, neutral background, no text, nothing distracting. Lifestyle shots, details and real life come afterwards, and they are worth a great deal: they are simply not the first one.

The ones that cut returns

Here we move from the channel to the person, and it is where images produce the most concrete return.

A scale reference. The single most effective intervention across entire categories. A known object next to the product, a hand, the model's height with the size worn. Without scale, buyers imagine, and imagining sometimes goes wrong and comes back.

Honest colour. A photo retouched to look better than reality produces an almost guaranteed return. It is worth adding a note when a colour is hard to reproduce.

The material close-up. A macro of the weave or the finish says things no adjective conveys, and it is what people look for when they cannot touch.

What is in the box. One photo with all the included pieces removes one of the most frequent questions there is, and one of the silliest reasons for a return.

The technical part that costs speed

Images are almost always the heaviest thing on a page, and speed matters both for buyers and for indexing.

Three things nearly always suffice: modern formats instead of enormous JPEGs, dimensions declared in the code so the page does not jump while loading, and deferred loading for everything below the fold, excluding the first shot, which must arrive immediately.

Layout shift while images load is particularly expensive: it makes people click the wrong thing, and it is the kind of irritation nobody reports, they just leave.

Alt text, and what it is actually for

The alt attribute exists for whoever cannot see the image: people using a screen reader, and machines. It needs a description of what is there, not a list of keywords.

"Black waterproof 30-litre backpack, front view" is useful to both. "backpack backpacks school backpack work backpack sale" is useful to nobody and is exactly the kind of thing engines learned to ignore twenty years ago.

Frequently asked questions

How many images does a product need?

Enough to answer the visual questions: what it is, what size it is, what it looks like close up, what is in the box. On many catalogues that is four or five. Forty near-identical photos help nobody and slow the page.

Does video replace photos?

It complements them, it does not replace them. Video is excellent for showing a product in use or its real size, but it cannot be a feed's main image, and many people never press play.

Are supplier photos fine?

They pass the checks and they do not differentiate: if every reseller uses the same photos, none of you has an advantage. Adding even two of your own shots, with scale and detail, is one of the highest-return jobs on a resold catalogue.

Is a white background required?

Not everywhere, but it is the least likely to be rejected and it also makes the product readable in a grid. For the first image it is the prudent choice; for the others you can do what you like.

Do images matter to answer engines?

Indirectly. An engine building an answer works on text and data, not on the photo. But alt text and file names are text, and they are the part of an image a machine can read.
