This short tutorial explains previous post more detailed.
Let's imagine we have personal automitive blog. Our blog has main page containing hronological feed of entries and separate pages for each blog entry conianing complete post. Also old blog's entries go to archive divided on many pages too. Without sharing tags between pages we will need to re-create tags for each image many times for each type of pages. Using tags sharing it will need to create tags only once.
Step 1: Generate widget HTML code with "Scope" parameter
At first step we generate widget HTML code using the wizard and doing the same actions as described in the post "How to add advanced tooltips for people on your photo" with only difference: we provide new parameter "Scope" that is simple string having clear meaning for you. As shown on the screenshot below scope may be even "abcde" string and it joins the set of pages sharing the same tags.

After code generated you need to add it to all pages those will share the same tags set. In our case those pages are main page, archive pages and blog post template.
Step 2: Create new post and visual tags
After post is created let's add tooltip which marks and describes car's engine on the photo. It's enough to create visual tag only once on the post page. You can see how it looks moving mouse over the picture below.
Step 3: It's all
Actually it's all - now this picture will automatically get the same visual tags on every page where you installed the widget code generated at step #1 , i.e. on the post page, main page and all archive pages.
Enjoy!
