All,
I don't know how to do it, but when I checked
php.net/manual/en/function.imagefilter.php
I came across the following php code for presenting images in greyscale:
<?php
$image = imagecreatefrompng('nathalie.png');
imagefilter($image, IMG_FILTER_GRAYSCALE);
imagepng($image, 'img_filter_grayscale.png');
imagedestroy($image);
?>
Would there be a way to integrate the above code with the Joomlapolis CB login (as a plugin?) so that site visitors would only see images in greyscale, yet logged in members would be able to see images in full colour?
Appreciate any suggestions.
Sincerely,
Customs
