@cool glad you discovered the issue. Sorry I couldn't be of more help, I got very busy.
Preloading background images
I remember when @baris or was it @julian one of you told me I should preload the images. Using jQuery, what would be the best way to preload the images? Right now, I believe my preloading method is ineffective as I am using CSS to preload the images. Right now I will have to optimize ALL of the images in my assets folder using PNG Crush and I am extremely tempted to using Varnish Cache with Nginx. Not sure about this yet. I've used it before and it was extremely effective but I'm sure thats a case-by-case basis.
What do you guys recommend?
If you have an array of images, just loop through them and prepend img tags to body; set a class for them to be display: none. For better performance set preloaded to a timestamp in localStorage and skip process on subsequent loads.
Also for you specifically, I noticed that you used to do an onHover effect for category images (I think it took greyscale to color) - best if you did that via a spritesheet rather than loading a brand new image.
There might be better solutions but throwing this out there
When's the last time you went to the site? There are no grayscale effects any more because it taxes the browser rending all of the effects.
I use a deferred method now as this article describes.
I pretty much check it every day. I had figured that you were just waiting to add those images back once you're happy with the layout and such
edit: so you're not? you know the category image thing I implemented in NodeBB was inspired by you right?
edit2: woahohoah, definitely what you have right now I did not see like 1-2 days ago. Very impressive!
Good god @trevor, you're blowing my mind.
