I thought the forum was a little slow, so I decided to forbidden the download of images especially for yui-lover.com :sry
But nothing changed. I didn't understand.
Then, I read the source and found that all the images were hosted on photobucket o_O
Maybe that's the reason for such a slowness. Why wouldn't you upload all main images on yui-lover.com?
I'm not sure exactly the reason of the slowness that you experience. Occasionally it might take a second or two longer to load the image for me, but I never really investigate into the cause whether if it's the image, photobucket, or whatever else.
This forum is actual using Invisionfree, which is a free forum service. For those that have been here last year or earlier, you may remember our address used to be like z14.invisionfree.com/YUI_Lover/. However, each forum account on Invisionfree only allows a maximum of 16MB of storage space. 16MB maybe enough for some forums, and it maybe to little for others. I think the admin chose to use outside storage partly because of that.
