I really don't know what to do about this. I suppose I could delete all the albums and upload them again, which would be ok. I kinda wish I knew what went wrong, though. I want to have the proper file permissions.
On my other site where the Images folder needs to be set to 777, the tech guys suggested uploading an .htaccess file in all the images directories with this snippet of code in it. I think it's resolved some problems people were having, with hacking:
`
<Files ~ "(^[0-9]+\.(gif|jpe?g|png)$)">
order allow,deny
allow from all
</Files>
order allow,deny
allow from none
`
You may add other extensions to that snippet. I'm thinking I might do this instead since changing the permissions hasn't worked out too good. But I need to get the site functional again before I can do this.
