you just don't understand, isn't it? have you looked at the content of the link? It has the full request life cycle and I don't call this technical. You don't need to move / copy images because this is dealt with automatically. Please do not use "what you have seen" to try and understand something much more complex than you think. When I say technical details, I mean multiple edge servers / global load balancers / firewall / distributed caching / DNS with Geo Location, etc, etc. Are you after the details of how the entire infrastructure can be implemented? Or do you call using SFTP to upload files "technical"?

Can anyone please tell me why sometimes my post is deleted without any notifications? Did my post violate some rules? At least someone should let me know why my post is deleted.

Hi, Why don't you take a look at the CDN article ?? Full content link: http://prestashopexchange.com/articles/cdn-or-not-should-i-use-cdn/ EDIT Table Of Content Introduction Should I use CDN? How CDN works The Request Cycle How does CDN invalidate cached objects? Performance Impact What would slow a Prestashop e-commerce site down? Is CDN the answer to performance? Increasing shop performance Move off shared hosting Optimizing PHP, Apache and MySQL Final words Introduction This article steams from a user question about the use of CDN and related questions around the CDN topic. The question is actually very simple but the, user, like many other Prestashop site owners, do not realize that there are more important ares needs to be considered before adopting a CDN. In this article, we will discuss whether or not CDN is appropriate for Prestashop e-commerce sites, alternatives to CDN and background technical knowledge Should I use CDN? This is probably not the first question Prestashop owners (shop owners) ask when starting an online shop, but will definitely be the one of the most popular questions shop owners ask themselves when the following happen: Growing amount of traffic, and predicted that additional capacity will be required in the near future. Obvious degrade in performance, especially during peak trading hours. Sometimes it is even worse, the whole site simply stop responding or takes too long to respond. Exceeding bandwidth limit, and the ISP is charging a lot of $$ per GB. The most obvious answer to the above seems to be Media Servers (or CDN) for PrestaShop owners. Since this is readily available from the Performance configuration screen, but how does it work? How will CDN improve the performance of your site? And more importantly, does it really helps and do you really need it?? Read on and find the answers below.

Take a look at the developer page, it's basically additional meta tag on the header telling facebook the image url

First you will need to know where the module is hooked to. There are different variables set to $smarty at various stages. Simple example: Product page: Hook header will only have id_product from request. Hook footer will have $product with almost everything you need. Best to work out what you need first, and where you need it and then consider to get it from $smarty or write simple queries to extract only what you need. Michael

would be a good idea to let me know what you are trying to do first?

Need better status update when an addon is submitted. The process should be shorten as well, I have been waiting for weeks for my little free addon...

There is already a tag cloud module??

Please PM me and send me URL of the site, etc. I will be able to do this

How about add a canonical URL meta tags? Take a look here http://www.seomoz.org/blog/canonical-url-tag-the-most-important-advancement-in-seo-practices-since-sitemaps
