Test for photo posting on perhaps the good-damned go.
Yeah, there are some definite difficulties with getting the image markup correct on account of unexplained demon line breaks.
Finally entering this from a desktop browser: The ability to enter WP posts via mobile is awesome. But be prepared for line-break editing if including any images in your mobile post. Also, while I assigned this post to the “Photos” category on my mobile device, it’s in “Uncategorized” as of a few seconds ago. I’m switching the category via browser interface now.
