Symfony PHP 1 and 2 coder to customize an existing website

This project is about customizing an existing website (free image host), made using Symfony PHP 1. Customization will make it possible to trigger an "action" when visitors click on specific places of the website. Action: a new tab opens (see sample image [login to view URL]), linking to a friend site url. Website administrator will have a field to enter manually the list of urls. Urls will be chosen in the order they appear. Once all are covered, the list will begin from the first url. Check attached sample ([login to view URL]) There are 5 specific places that activate the Action when visitors click on them: *the 3rd thumbnail (from left to right) of every row in the mainpage *each 3rd thumbnail (from top to bottom) on the right and left columns *the 3rd thumbnail (from left to right) of every row in the Similar posts section *the 3rd thumbnail (from left to right) in the image carrousel. *the 3rd thumbnail (from left to right) of every row in category pages Note: when the action is triggered, the site works as normal (the internal gallery is opened, and also the new tab opens). For categorized content, webmaster will be able to define related friend site urls. For this, on the Category menu of the admin panel, a field will be added to associate friend site links to specific categories. Check attached sample ([login to view URL]) If the field is left empty (no urls are entered) for a particular category, no action triggers inside that particular category. For uncategorized content (in case content has no category), the user will be able to define generic urls in a field located in settings page. Check attached sample. ([login to view URL]) If there are no friend urls assigned for uncategorized content, no action triggers for uncategorized content. test environment is provided for all practices.
