Testing photo loading again
Yet, there's the obligatory cute cat picture showing up just as desired.
It also turned out that my other problem (that trying to edit a published post fed me a blank Compose page) was not the problem I thought it was. It was a problem of the speed of data load not matching my impatient nature. In other words: if I hit Edit on an existing blog post, the Compose page comes up, and it comes up blank. Which is freaky, as I'm sure all of you bloggers can appreciate. However, if I had actually waited a few seconds eventaully the data for the post does appear. I still think it's a problem of a way-too-slow loading time. But that's not quite the urgent and tragic problem of not loading the data at all and being unable to edit!
