Can I delete entries from qa_blobs when I am sure that those images are not used in any question or post?

 

Actually I did so, but clicking on "filename" now (to sort the entries) returns:

MySQL returned an empty result set (i.e. zero rows).

?

 

The mysql for sorting is:

SELECT *
FROM `qa_blobs`
ORDER BY `qa_blobs`.`filename` ASC
LIMIT 300 , 30

// 300 ? strange

 

Update: Now sorting works, I logged out, and cleared the cache of my browser.
