I've been trying to tell you that Word can insert cross-references that ARE
hyperlinks. If you caption the figures using Insert > Caption, then in your
body text you can insert a cross-reference to the caption.
You can format the cross-reference to look exactly like a web page
hyperlink. The cross-reference text will be some variation of the caption --
just the text part if you like.
If that's not good enough, you can select each picture and click Insert >
Bookmark to bookmark the image. Then you can create a hyperlink (Insert >
Hyperlink) and select the bookmark you want to jump to, the displayed text of
the hyperlink, and the hover tooltip.
In all cases, clicking such a link opens the Web toolbar which includes a
"Go Back" button.
If this built-in hypertext functionality is not good enough for you, then
you could create hyperlinks using MacroButton fields.
You can set the displayed text, format, and number of clicks for the macro
button. You can use an acutal button image if you want. The macro itself
would select and display the figure. It would then display a custom-made
toolbar with only a Back button. Clicking that button would launch another
macro that would hide the toolbar, select the original hyperlink, and
redisplay the "jump off" point.
Alternately, you could use a macrobutton to create a permanent "Go Back"
button beside or below every figure. Each one could use the same macro, but
you'd have to record the source hyperlink location in a document variable so
the macro would know where to jump back to.
What you're asking is to build a custom hyperlink application, and you
certainly can do that. But the built-in hyperlink functions of Word are
pretty flexible as they are.
Please contact me off-list if you'd like me to work up a sample document
showing you what's possible. Even better, you could send me a draft of one of
your documents and I could wire it up with examples.
