the site has slowed way down in past 16 hours. uploading is almost impossible.
It seems normal to me now. Also we have a system the authomatically logs every time a page was generated in more than 2 secs. Are you sure that it wasn't a problem with your adsl? The whole site was slow or just the uploader?
Interesting, so the problem maybe happens because we convert every other format to jpeg. Does this problem happen every time you upload some pngs?
