Lack of interest Disable permission check attachments when not necessary

[dutchbb]

In image heavy threads every image is checked for correct permissions of viewer if i am correct. When you show attachments to guest this happens also? If so it seems unnecessary to me and a lot of extra query's that could be avoided.

So an option to fully disable persmission check with attachments would be great. (or a file edit option if this is not a good idea).
