By default, all images on online store pages are loaded at the same time, resulting in slower loading speeds, pessimized search queries, longer wait times, and poorer user experience.
Why it's important:
What can be done?
A simple solution is to postpone downloading anything that is not needed by the user right now. To do this, we have developed an add-on "Deferred Image Upload", which only uploads images when they are visible to the user. The rest of the images are loaded as the page scrolls. This speeds up page loading and reduces resource consumption.
This optimization method is especially useful for sites with a large number of images, such as online stores, pages with a large number of images, photo galleries or portfolios.
According to the results of our measurements on a test site (100 products and 4 banners were placed on the page) :
The add-on is easy to install and requires no additional settings.
After downloading the add-on, it can be installed using the standard CS-Cart tools on the page Admin Panel → Add-ons → Manage Add-ons → Upload and Install Add-on (+).
For CS-Cart version 4.13.1 or later, go to Admin Panel → Add-ons → Manage Add-ons → Gear Icon → Manual installation.
After installation, the add-on is ready to work.
The add-on has a single setting Use external js component.
In some cases, it may be necessary to download the JavaScript library from an external source for the add-on to work correctly. This may apply to situations where images or other media elements, such as brand logos, are not displayed properly.
