I noticed a couple of things while I was putting together my responses to the icon meme.
The question:
The first Tin Man icon that I made for myself had the keyword "Glitch" and looked like this:
When I was going through my icons for the meme I noticed that it had been replaced by this image:
WTF?
Moreover, I couldn't simply reupload the old icon to the keyword "Glitch" - it would tell me the icon was successfully uploaded, but the new one was still there with that keyword and the number of icons had not changed. (Normally the more recent upload would appear with the keyword and the earlier one would still be there but with "pic #xxxxxxx" instead of the keyword.) I tried changing the new one's keyword but it wouldn't change. I uploaded the old one to a new keyword and when the dust cleared, the new one was there under the new keyword! Finally I just deleted the new one - I was pleasantly surprised that it worked - and had no difficulty uploading the old one to its original keyword.
What on earth was that all about? Is this some kind of nuisance hack going around?
The observation: I've replaced the Glitch icon, but look - the direct link to the ersatz one still works! After I posted the icon meme, I realized that I had forgotten the border on the fourth Court Jester icon and that a few of the icons (like the "Just Gotta Hug" Joey/Chandler icon) still hadn't been corrected to look right in Firefox. Now, when you reupload an icon, all previous uses of that icon qua icon will now point to the new version. BUT direct links to where it's stored (the URL with the TLD "p-userpic") do NOT change. The old versions are still there! The new version is stored at a different URL. TSo I had to find the new URL's and redo the links in order for the new versions of the icons to show in the post.
LJ must have a heckuva lot of icon-storage space ...
ETA: Some of you see Glitch plus the interloper; some of you see two Glitches! Here's what I see (it's a screen capture, hence the partial text):
