hi,
i don't know where you hosting your site, but your server admin should know that every php upload process over a webbrowser will upload files as webserver user and not as your userid
example
-rw-rw-rw- 1 wwwrun www 51435 Aug 26 18:41 P1010003.jpg
or in your case
-rw-rw-rw- 1 99 99 51435 Aug 26 18:41 P1010003.jpg
well, what he can do for you:
he should go with his SSH client to your data folder and do following
linux:/home/account/4images/data # chown -R YOURUSERID:YOURGROUP *
OR
you have to download all data folders (including pics of course) to your pc.
delete the folders and images on your server..
then upload the folders again to the server...
BUT do that just where is the owner/group 99
hope this will help...
