[TYPO3-core] RFC: bug#3522 Linking images to hidden pages results in click-enlarge

[Ernesto Baschny [cron IT]]

This is a CVS patch request

Type:
	Minor bugfix

Problem:
	Linking images to currently unavailable pages (hidden,
	restricted due to FE-permissions or timebased restrictions)
	results in a click-enlarge of that image instead.

	Reproduce with:

	- create an "Images" content element with just one image
	- link that image with some hidden page
	- render that page in FE and click on the image

Solution:
	Current TS to "enable" the click-enlarge relies on the
	assumption that typolink will generate a link out of something
	filled in the "image_link" field. But when typolink doesn't
	(e.g. page is hidden), the click-enlarge is generated instead.

	Solution is to check if typolink would generate a link instead
	relying on the non-emptyness of the "image_link" field.	

Branches:
	HEAD and TYPO3_4-0

Bugtracker reference:
	http://bugs.typo3.org/view.php?id=3522

	bug-3522.diff attached


Further comment: This also affects "content (default)". As I don't know
how to make a patch for that static template, this is currently not
handled by this diff. See previous thread.

Cheers,
Ernesto
