Hey,
1) It’s not possible to have the same effect as with the lightbox link, but you could have it fade out a bit on hover, by adding this custom CSS in the General theme options:
.img-link:hover {
opacity: 0.5;
}
2) Not sure what header, but GIFs are also images, so those can be used. FLASH not really, maybe if you need it inside the content area, you could embed a flash movie, yes.
3) If you need to hide the main navigation, add this custom CSS:
#nav-section {
display: none !important;
}
Regards,
