making a link active?

[markhaldanephotography]

Im trying to make a link only become active once a script has finished running

what im trying to achieve can be seen here:

the enter button is there, and can be clicked at any time, even before the
"preloading" script is finished... I need to make it so that the ENTER button
CANNOT be clicked until the "preloading" script has finished running

Alternatively, having the enter button not appear until the loading is done
would work just as well

If there is a solution to this problem please help me out with it :)

Assuming the image preloader is javascript

Set the "Enter" button visiblity to "hidden" and disable it

Then when the JS is finished loading the images, just set the visibilty to
"visible" and disable = false
