Hello,
I've noticed that alot of images load when WWF is first loaded in a browser. There's about 20 or so objects which means alot of HTTP requests and latency due to these requests.
Could sprites be developed to combine images so that this loading performance issue dissapears?
Although WWF content is generated super fast on the server- this is fairly standard, most decent ASP applications execute very quickly and send out there wonderful dynamic creation in a very short time. Which is usually only 20% or less of the actual users experience of the loading time. The rest is image + css + javascript etc - and the latency that goes with them.
I recently read an article, this one:
http://yuiblog.com/blog/2006/11/28/performance-research-part-1/
It's not an amazing article but it's pretty cool to take into account the factors mentioned.
Days earlier I had noticed that even on my fast connection the very first load of WWF on an empty cache is a little bit slowed- based on latency of lots of small images I reckon.
Anyway WWF is absolutely excellent, but I just thought I'd bring up this point for consideration.
What do people think?

It is an interesting idea to use CSS Sprite Images, and web wiz forums already uses this for things like the button images and tabs.
However, the problem with doing this throughout the forum is that it would make it much header for people to modify the images in the forum, particularly if the replacement images are not exactly the same size. The image size issue is one of the reasons why Web Wiz Forums doesn't set the image sizes so you can replace images with different sizes.
One area where it maybe useful to include is in the post editor buttons as there are quite a few images there which do slow down load times and the button images tend to need to be changed with images of the same size.
