How can I create hyperlinks to a specific ITEM on another page of the same site?
Suppose you have:
a page with thumbnails organized in six distinct groups, let’s call that page “catalogue”.
and
six additional pages containing each of the groups of images ( much larger, for edification ).
Clicking on thumbnails on the "catalogue "
would open the page corresponding to its specific group,
with those particular images ( corresponding to the thumbnails ) centered on the screen.
You can target an Anchor on another page using the link anotherpage.html#anchorname
in FW you would select your image that you want to anchor to and use Edit>Anchor. Give your anchor a suitable name and OK the dialogue box.
Now on the page you want to link from create a hyperlink as per normal and choose the page you wish to link to. Once you have selected the page you want to link to there is a dropdown (Anchor) that will list all available anchors on that page. Select the one you want.
As to getting the image to be in the centre you will need to construct your page carefully to achieve that as a selected anchor will appear at the top of the newly opened page.
