replace_failed_smilies_with_alt_text details:

Spoiler:

## SV & SB (and possibly QQ and AH) like to use sprite smilies --
## smiley images that are all in one image file for performance and
## are shown by CSS background with offsets.  Epub viewers don't like
## that.
##
## The sprite smiley img tags generally do have alt attributes that get
## the point across: ":)" ":D" ":(" ":lol" etc.  And not all smilies
## on these sites use sprite images, so some can be used as is.
##
## When replace_failed_smilies_with_alt_text:true, any images that
## failed to download or are src=clear.png *and* have a class containing
## mceSmilie and an alt attribute will be replaced with:
## <span class="(classes)">(alt text)</span>
##
## The smiley classes are preserved in case the user wants to do
## something special with them.
