Short checklist tied to what described and asked: Adaptive-Images is a small PHP solution that needs PHP + the GD image library, an .htaccess that the server actually reads, and a writable cache folder. On localhost those three are the most common blockers (GD missing, .htaccess ignored, ai-cache not writable). (github.com)

Quick tests you can run right now. Put this file in your htdocs and open it in the browser to verify GD is available:

<?php
if (function_exists('gd_info')) {
  var_dump(gd_info());
} else {
  echo "GD not installed";
}
?>

If GD is missing: on Windows/XAMPP edit php.ini and enable the gd extension (uncomment or add extension=gd / extension=php_gd.dll), then restart Apache. On Debian/Ubuntu install the package (e.g. sudo apt install php-gd) and restart Apache/PHP-FPM. (php.net)

Make sure Apache is actually processing your .htaccess rules: enable mod_rewrite and allow per-directory overrides (often sudo a2enmod rewrite and set AllowOverride All for your site), then restart Apache. Check the server error log if the rewrite rule causes a 500. If .htaccess is ignored the adaptive script never runs. (httpd.apache.org)

Folder and cookie notes: create the cache folder and give the webserver ownership (adjust user for your distro; common examples shown):

mkdir -p /path/to/ai-cache
sudo chown -R www-data:www-data /path/to/ai-cache
sudo chmod -R 755 /path/to/ai-cache

Also ensure the tiny JS that sets the resolution cookie is placed inline high in <head> (race conditions can cause the browser to request images before the cookie exists). Finally: if this is a new project, prefer native srcset/picture for responsive images — they’re simpler and better supported long-term. Example and docs: (developer.mozilla.org)

If these checks still show no activity, paste the output from the GD test and the exact .htaccess you used so the next steps can focus on specific errors.

it doesn't work for me.

Doesn't work is too vague. What have you done, what did you expect, and what isn't working? Do you have an example?

Member Avatar for pritaeas

Do you have the GD extension? Does the cache folder exist? Is it set with write permissions?
