when including a pic in your post that you get into the habit of appending (PIC) or something similar onto the subject line to inform others that there is a picture included.  Too many times I've clicked on a post, when there may be others within viewing distance of my monitor, and a full screen, risque pic of a lovely lady pops up unexpectedly.  Not cool for me.

Also, after all the strong opinions about posts with YouTube videos, if the content of your post is exclusively a YouTube link (ahem, Giselle), append (VID) or something similar onto the subject line so that those who aren't interested in such posts can avoid clicking on them, thus preventing further board drama.
