There are plenty of other similar things out there, but Picasa is generally so good that I can't be bothered to check out the others.
Often, when I start a blog post, i pick up the images I need in Picasa, hit the 'Blog This' button at the bottom, and post them to a draft in Blogger's editing console, then I do the text within blogger. It's quick and simple and I'm used to it.
Recently, that's not been working, hitting 'Blog This' just gets me an error code. The nub of that error is:
rss: Required field must not be blank
Simple enough? No. Because there's no rss field that you can fill in. So of course, I do what picasa asks, delete cache and cookies, sweep out all the accumulated crap from my browser, and the problem's still there. I look up Picasa Help, no help. Forums, no help. This is Google, so there's no easy way to report a problem or contact support people. Then, after an age of googling, I find this
How to Fix Blog This Function
Update: I took some more time browsing for answers. "Update Picasa"? So I go to the Picasa update checker "You already have the most recent version" Well of course I do, because I ticked the "enable auto-updates" option. But being a belt and braces sort of bloke, I decide to go to the Picasa download site and reinstall it.
Magic. It works. Why? I don't know. Do I take back my grumbling?
NO I DO NOT DAMMIT!
If a developers deliberately screws up a feature, then the users should be informed, not left to waste their time trying to mend the unmendable.
