Yupoo conducted an upgrade on the morning of January 10, 2008. This upgrade had a significant impact on many users, primarily because image hotlinking addresses will now be provided separately. Image URLs will be used separately for inside and outside the site. Images used within the site will not support hotlinking, while external addresses for image hotlinking will be provided separately. Meanwhile, previous image hotlinks will remain unaffected, and their addresses will not change.
