Correct answer JoelGeraci_Datalogics

I should have been more explicit.

You'd start by adding a button field the size of the zoomed image and setting the Up icon to the image you want. Set that field to be hidden by default and set it's Up action to show/hide a field and select the same field. That way when the button is showing, clicking it will hide the field. The add a link to your document on the image that you want to trigger the zoom. Set it's action to show/hide the big button field. Clicking the link will show the big button, clicking the big button will then hide it.

I was just exploring the button function, look quite similar to link option. Can you explain more your idea? What do you mean by using the image as a button face? To make the button transparent in front of the small image? If I open read mode and click on the button then it does the set action, like opens a file what would be good for me at this point if I could get back to my pdf from there.

Great, I was already typing that it's too hard for me to get it, but I finally succeeded! Thank you Joel, that's a nice trick!

Ehh, sounds bad - sad that it's probably too difficult for me. Maybe it is possible to simply link the thumbnail to a page with an image all ower the page ... Only that it will be also ugly to have some misteriouse set of image-pages in the end of the file.

You could also create a large button that uses the image as a button face. Clicking on the small image would show the button, clicking on the large button would hide it. It won't float but it'd be easy to implement without scripting.

You could do something like that using an Acrobat JavaScript dialog but you'd need to base 64 encode the enlarged image for the dialog box to display it.
