However, about 75% of these hotlinked images display for a minute and then break and display a broken image graphic.
You've learned something useful here and I wish all forum members everywhere* would understand it. Please try to spread the word. When you're putting up a post including an image link, look at the post in a different browser. It isn't only caching; the site may have set a cookie that tells it you're allowed to view that particular file. Few things are more exasperating than reading a long lead-in and then slamming into a NO HOTLINKS icon in place of the promised picture of your cat doing something adorable.
This applies just as much to deep links as to hotlinks; the site can't tell the difference.
Edit: Oh, c'mon, Leo. I could post a link to a picture hosted on my own site and that would be a hotlink in every sense of the word. The site owner's permission, or lack thereof, plays no role in the definition of a hotlink.
* Present company excepted, if only because this forum doesn't "do" images.
