I received from my hosting that we use many resources with your plugin by generating each time tumbs for list of articles.
The message is:
Once it generates thumbnail, generated image should be put directly to the source image, not to go every time to the timthumb.php. For example in this page http://www.bucatareselevesele.ro/retete-culinare/retete-bauturi.html It is called the PHP engine 33 times when they could completely avoid these calls.
There should be direct links to pictures and not pass it through a php file: /wp-content/plugins/category-grid-view-gallery/includes/timthumb.php
Is there a solution?
