About Slideshows – please do not read more unless you’re genuinely interested. 😎
WordPress have, yet again, changed the code (JScript) and style sheet (CSS) for the slideshow facility, thereby buggering up the careful tailoring I had added to give The Chariot‘s slideshows a ‘look and feel’ that better matched our template (‘house style’).
I have made what css changes I can to rectify the situation, but WordPress.com users cannot, as you know, access the code, so the result is a compromise.  Depending on the size and shape of your pictures, you may, or may not, find that the caption bar obscures the bottom edge slightly.  Apologies if it does, but that, unfortunately, is the way the cookie currently crumbles.
I have no doubt that WordPress will change their design yet again over the coming weeks; they have amended it several times already. 😎
