So I tried colorbox and various other lightbox-type modules, but Lightbox2 seems to be the only one that supports video out of the box with simple setup... But the image loading is unbearably slow.

I have a Lightbox Trigger in a view that loads 10 images attached to a node. The are all being resized via imagecache. But even after the images are generated, cycling next/prev through the lightbox modal window is really slow.

It's not the animations, I've turned those to 0 and then even 2 seconds, and timed it- animation by animation, and its just the image loading that is slow.

It will open the lightbox modal, pause for 2.5 to 3 seconds, and then load the image. Clicking next repeats the 2.5 to 3 second pause, and then loads the image again. The whole time- I'm left thinking the module isn't working because no image is showing. Then, all of a sudden it pops up.

I'm running through acquia-drupal locally right now, and made sure that the compression options that are available are being used, and the image size is less than 100kb per image.

Is there something I can do to make this faster?

figured out that it's either the administrator menu module that adds a lot of page items, or it's the ads module in anything but "raw" display mode.
changing the ads to raw, and logging out of the admin account makes the site load much faster- as well as lightbox2.

EDIT: looks like it's the admin module or something on the admin side... logged back in and it was slow to load images again.
