Lazy Load for Images and Blocks

Postpones the loading of images and blocks beyond the first screen — they load as the visitor scrolls to them. The first screen appears faster, layout shifts disappear, and the page feels lighter.

Lazy Load for Images and Blocks
Lazy Load for Images and Blocks
$60.00

By default CS-Cart loads every image on the page at once, including the ones far below the fold that most visitors never scroll to. The visitor waits for pictures they will not see — and waiting is the most expensive thing a store can ask of them.

Why it matters

  • A tenth of a second of extra load time costs around 7% of conversion, by Akamai's measurements.
  • A poor experience reduces the chance of a repeat purchase by up to 60%, according to Google.
  • A slow site is crawled less thoroughly: the robot may not get through everything it should.

What the add-on does

  • Postpones the loading of images beyond the first screen — they load as they enter the viewport.
  • Does the same for content blocks, not only images.
  • Improves LCP, the time the main content takes to appear — one of the metrics search engines weigh.
  • Reduces CLS, the layout shifting that makes a page feel unstable while it loads.
  • Speeds up the first screen without removing anything from the page.

Images loading as the visitor scrolls

What to keep in mind

The add-on is not compatible with the UniTheme2 theme. On such projects the other speed tools — image compression, WebP and resource preloading — still apply.

Support and updates

The settings are covered in the documentation. Six months of free updates, questions through HelpDesk.

FAQ

Will images below the fold still be indexed?

Lazy loading is a standard technique that search engines handle; the images stay in the page markup and load as the viewport reaches them.

Does it work for blocks as well as images?

Yes, content blocks beyond the first screen are postponed too.

What about UniTheme2?

The add-on is not compatible with it — use the other speed add-ons on those projects.

Используем модуль в течении 5 месяцев и получили прирост на 21 пункт для мобильной версии темы Uni 1 и на 30 (!) для версии ПК. Отличный результат по загрузке изображений и расширенных баннеров, сайт визуально стал загружаться быстрее. Модуль имеет гибкую систему управления пост загрузки изображений категорий, в товарных карточках, баннеров и изображений в различных блоках. Что ещё данный модуль поддерживает cs-cart c версии 4.6.3. Рекомендуем)

У вас скрины до и после, одиннаковые. Ваш модуль лучше чем cs-coding, он грузит фотки при видимости или всё сразу после загрузки страницы, видимые и не видимые? Совместимо с АБ шаблонами, дайте плз инфу на почту, я закажу.

Flagship products

Two add-ons that change how a store performs

Everything else we publish improves one screen. These two change the numbers: how customers find products, and how often they come back.

 

Add-on · Search & merchandising

Smart Search

Elasticsearch-powered search for large catalogues. The customer types two letters, sees products with images and prices, and buys from the dropdown — even after a typo or with the wrong keyboard layout.

Visitors who use the search bar are 24% of traffic and 44% of revenue, and convert about 2.5× better than people who only browse categories. If search returns nothing, up to 80% of them leave.
Constructor, Beyond Relevance Report 2025; Google Cloud × The Harris Poll, 2023

Catalogue size Sub-second results on 300,000+ products, Multi-Vendor included
Understands Typos, wrong keyboard layout, synonyms, word forms, SKUs, brands and attributes
Reporting Query analytics — what customers search for and which searches return nothing
Deployment Our cloud, or Elasticsearch on your own server

from $35/month

Plans by catalogue size · self-hosted from $1,215 one-time

Try it on a live catalogue: open the demo store and search with a deliberate typo.

 

Add-on · Mobile commerce

PowerApp — mobile app for your store

A native iOS and Android app running on your CS-Cart data: the same products, prices, stock, promotions, reward points and orders. There is no second catalogue to maintain — everything stays in the admin panel you already use.

A mobile site brings a customer in once; an app brings them back for free. Push notifications replace the retargeting budget you spend to buy the same customer a second time.

Platforms Native iOS and Android, published under your own developer account
Home screen Built in the admin panel from six block types, the same way you build website pages
Time to launch Under a week from purchase to submission for App Store and Google Play review
Compatibility CS-Cart and Multi-Vendor 4.18–4.20 · 11 client apps already live in the stores

Services

When no add-on solves it, we do the work

Fixed scope, written specification, a named project manager and a warranty on what we ship.

Custom CS-Cart development

Functionality the platform does not have: add-ons, marketplace mechanics, integrations with 1C, CRM, ERP, payment and delivery providers. We start from a written specification, not from an estimate on a phone call. Details →

CS-Cart upgrade

Move to the current version without losing data, custom code or add-ons. We audit every modification first, upgrade on a staging copy, adapt what breaks and switch over with little or no downtime. Details →

Speed and performance optimisation

Conversion falls by about 4.4% for every extra second of load time. We profile the server, the database and the front-end, then fix what actually costs the seconds — and show you the before-and-after numbers. Details →

Design for CS-Cart

Mobile-first storefront design built on CS-Cart's own template structure, so the layout survives the next platform upgrade instead of becoming a migration problem. Details →

SEO for CS-Cart

A technical audit of indexing, duplicates, redirects, structured data and Core Web Vitals — delivered as a prioritised fix list your developers can act on, or that we implement ourselves. Details →

How we work

What you get besides the code

Before we start

We discuss the goal, offer options and write the specification. You approve scope and price before development begins.

While we build

A named project manager reports progress on a fixed schedule. You always know what is in work and what is next.

Before release

A separate QA pass on every release — the developer who wrote the code is not the person who signs it off.

After handover

Documentation for everything we ship, plus a warranty on the modifications and the project.

Tell us what the store needs to do

Describe the task in a couple of sentences and we will come back with options, a scope and a price. The consultation is free, and we will say plainly if a ready-made add-on already solves it.
