Speeds up rendering time for a page with many pictures.

TYPO3 CMS renders all the pictures on a page during the first request. On a page with many pictures this can lead to a long waiting time or even a server timeout.

This extension allows TYPO3 CMS to render pictures asynchronous.

Install extension.

Add following code to your .htaccess file:

<IfModule mod_rewrite.c>
   RewriteEngine On
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} /_processed_/
   RewriteRule ^.*$ %{ENV:CWD}index.php?eID=image_async_process [QSA,L]
</IfModule>

How it works?

This extensions uses a file processing slot for caching image processing information and returning a dummy processed file instance. When a browser requests a not existing image, TYPO3 CMS will render it.
