So I thought I'd test it at 50 just to see if the setting was having any effect, and I still couldn't see any difference. The cover always looks the same as it did before the tweak (when the level was 70). I cannot get it to look like the version you showed the other day.

I restarted Calibre after every setting change. What am I doing wrong? Is there another setting someplace else that also has to be changed? Is it my Nook HD somehow or ICS?
Pat,

Covers are resent only if the metadata changes in some way (the last modified date changes). Changing the value of the device preference does not touch the last modified date, so probably nothing is being sent to CC.

You can test this with Mudbound by selecting the book, pressing E to open the metadata edit dialog, pressing OK without changing anything, then connecting CC. You should see it download metadata for at least one book, and the cover image should change.

After verifying that the cover did in fact change after you do the above, if you want to resend all your covers then you must change the last modified date on all books. There are several ways to do that.
1) When a device is not connected, press the down arrow next to the library toolbar button, choose Library Maintenance, Library metadata backup status, then press Queue all books for backup.
2) If you have a "column built from other columns" (a composite column), click on that cell for any book, press F2 to edit the template, then press OK.
3) Go to Preferences, Add you own columns. Choose any custom column, press the I button to open the column's properties, then press OK. Restart calibre.

Also, by "tweak" I assume you mean the setting in the smart device driver plugin. True?
