In the plant ID forum I had this message come up in three out of four tries - all different images. These are the ones I tried.
The thread "Unknown begonia." in Plant ID forum
The thread "small tree of unknown species" in Plant ID forum

Firefox and Windows7.

Is it just my system?

I'm suspecting it's an internet timeout. Since nobody else is reporting this I'm thinking it's probably on your side of things. Has this continued through today?

All four loaded right up today, Dave.

It must have been my internet connection. It does slow down here in times of heavy usage. This was just the first time I'd seen this message along with a total failure.

Thank you.

A speed bump on the information superhighway.
