While writing my last blog post, Lifehacker search plugin for Firefox 2, I had several screenshots I wanted to upload, but WordPress continually rejected them. I was forced to upload them to another site, and link them all externally. This is the error message I received:
In the last half-hour, I have been able to upload some images, but it is intermittent, and I have still received the error message several times.
Is anyone else having this problem?
UPDATE: I think I may have been trying to upload pictures that had spaces in the filename, so no wonder they didn’t work! This FAQ set me straight – though experiment reveals that dashes (-) and underscores (_) are OK as well, in addition to letters and numbers. Do’h!

Spaces in filenames are almost always a no-no. All kinds of programs get confused by them.

I’m used to using spaces in filenames and folders quite liberally on my PC, but as a web publishing noob, I need to get used to swapping out those spaces for underscores or dashes whenever I upload files.
