I have the exact same problem.. I found one link to a topic but the link is a dead end.. can anyone help on this? I can login with admin or directly in the nuke modules/4images folder but when in the nuke site when you click on the module link to the gallery it comes up with a blank page saying "Hacking attempt" (/modules.php?name=4images)
All URLs appear to be correct and all db info seems ok
