Images wont display when viewing articles, Need Help

[complexs]

I'm not sure how to search for the attachment # in the database if you could tell me I'd appreciate it.

If I edit the articles I see no images at all expect the one that I recently uploaded today.

I don't know if my attachments are stored on the filesystem or database, could you tell me which one is better and how I find out?

Thanks

I would also like to add now even thumbnails do not work. So ALL my images are broken basically, except the one I uploaded right when I was noticing this was happening.

Okay sorry for the second post but I found out my attachments are being stored on my databased.

I also noticed I was playing around in the "vBulletin Blog" Section, within Update Counters.

Okay, I just received huge amounts of emails in regards to vbulletin database errors and I just checked and my website is down!!!


Here is the first and second vbulletin database error email:

Database error in vBulletin :

Cannot use database "my database name"

MySQL Error : Unknown database
"my database name"
Error Number :1049


Here is the third email:

Database error in vBulletin 4.1.7:

SET locktime = 1334734313
WHERE cacheid =
'cms_priv.6f6fbe6ae9734175cef145747cbfd6c0';

MySQL Error : Incorrect key file for table "./mydatabasename@002dpc/cache.MYI'; try to repair it

Here is the fourth email:

Database error in vBulletin 4.1.7:

Invalid SQL:

SELECT data, expires, locktime,

Here is another email:

Database error in vBulletin 4.1.7:

I have tons of emails looking very similar to the last two emails above. I turned my domain names servers somewhere else since I assumed it was a MySQL injection or some sort of hack. I need help please.
