problem with uploading of files

I dont know if it is just me, but it seems that the site having problem uploading my pics. I upload them as usual and the site accepts them and shows them as published. But after a while they show up as not published. I have refreshed my acount and even the site. The pics then shows as published again but as soon I leave the site and comes back they show as not published again. This goes for both on site made pics and of site made pics. I eaven tried to reupload them but with the same results. So if you can't see them I hope that this is just a temporaily glitch in the system and that you will be able to see them soon.
