Stackla uses a multi-step process to ensure all aggregated images that are displayed are valid and working as expected.
This process is called crowdsourcing and relies on Stackla users to notify the system of any issues. To avoid potential abuse of this method, only one notice per IP address per tile per hour is allowed.
For Instagram and Facebook images which are flagged as broken by the crowdsource process, an additional step occurs whereby the Stackla system attempts to validate the URL of the tile, and if it’s deemed as broken from the server side, it will try to retrieve a fresh “good” URL from the Instagram and Facebook APIs. If this also fails then, as above the tile will be marked as 'Disabled' and the tile’s disabled reason will also be set to "Broken image”.
This process has been put in place to protect client's who are using Event Screens, Widgets and other display methods from creating a poor user experience. For example, If the third-party service which hosts images can’t keep up with the widget traffic or a widget has been improperly configured to display many oversized (eg. high res or with a large file size) images, Stackla will ensure the speed, stability and quality of the content it’s attempting to display.
For example, if your third-party service that hosts images is unable to keep up with the Widget traffic, or a Widget has been improperly configured to display several oversized (eg. high res or with a large file size) images, then your content may be flagged as 'broken'.
