Blogger only displays some images in Lightbox

Just solved this one for myself. I've got a page (Hordeboloods) that for formatting reasons, I create in Dreamweaver, then copy the code to a Blogger post whenever I want to update it. Noticed an image that the browser would just open instead of displaying in the lightbox display.

Here's how I solved it:

I compared the image to some of my other images, found some discrepancies and the problem ended up being the "alt" property of the image. Even if you don't have any text in the alt text, it appears you need it. Make sure your IMG tag contains:


or with a description.

There are a few other differences. There's an imageanchor tag in the A link, the link and the image path had different paths, but changing these (even after I got it working) didn't change whether it worked or not.

Schrodinger's Backups

A comment on a cautionary tale from Spiceworks offers a wealth of IT insight:

Schrodinger's Backups:
"When you are not testing them the backups are both there and not there at the same time."
- Wilkins IT Solutions (Though I don't know the original source of this quote.)

Apparently this is a thing. What's this mean? The Schrodinger Cat theory basically boils down to a situation where two states are considered true at the same time until someone checks them. In the case of the cat, you've got a cat in a box that will be poisoned at an unknown time, therefor without looking in the box, the cat is considered to be both alive and dead. (Personally, I'd say it's "unknown" not in both states, but hey, what do I know of quantum mechanics?)

So, you're doing backups? Great. Do they work? Have you ever tested restoring even one?

In this case, backup files physically exist, but without testing them, you don't really know if the backup is valid.

Recycle Bin Backup Files

Came across this over on FailDesk and my how it brought me back to an incident I dealt with / created once. We had issues with the Exchange server filling up and while users weren't bad about deleting large emails or backing them up to local PST's, they never emptied their Deleted Items. This led to full mailboxes and serious performance issues.

I had the bright idea to instigate a group policy that emptied Deleted Items when they closed Outlook. This worked great and quickly managed everyone's accounts for them. Until... "All my important emails are gone!" What? Turns out. A user who, yes, had what I would consider important emails, turned out to use a rather peculiar method of record keeping. They stored emails they wanted out of sight that they'd dealt with, but might have to reference later, in the Deleted Items. What? When they were done with them for sure, that's when they'd manually remove them permanently. (These were emails I probably would have stored, not even deleted.)

So, that caused a bit of an incident. The user could not be convinced that storing emails in the trash was unwise. I believe I was able to restore the emails in question, but wow. Moving forward, I left the GPO in place and it solved a lot of email woes.
