New feature has been intoduced recently which allow to share tags for the same image between different pages.
Previously scope of the tag was restricted by the page where it is created. If you have the image which is displayed on 2 pages and want to show the same tags for it on both pages you was needed to create these tags twice for each page since tags created on one page didn't work on other page.
Now you have a possibility to share tags between pages without re-creating them for each page. For that use new Taggify wizard parameter named "Scope".
If two pages contain the widget code generated with the same value of parameter "Scope" then these pages will share tags for the same images. You will need to create tags for the image only once and then these tags will be shown for that image on all pages having the same parameter "Scope".
If you do not specify "Scope" parameter then widget will work as earlier, i.e. scope of tags will be restricted by the page of their creation.
NOTE: Please use "Scope" parameter with a caution since it may affect on how fast your website is loading in the browser.
Imagine your website has a lot of pages each containing many images with many tags. If most of images are presented on single page only but all pages share the same "scope" then it will cause a lot of unnecessary traffic from server to visitor's browser for sending all tags for all existent images for each page and the website will be loading slowly.
Use the same scope parameters only for pages having the same images with the same tags.
