New themes, fixed comments

The comments weren’t working – they should be OK now.

I added a couple of themes, Imbalance and Paragrams. (Thanks Paul for the tip-off.) They’re intended for image-based blogs. To have a post image feature on the front page of the blog, you will have to select a ‘featured image’ when making a new post. With these themes, the option to do that is on the right hand side of the ‘Edit Post’ page. (This doesn’t appear when using other themes.)

To change the header title in a blog using one of these themes, you’ll need to create your own image. Go into Appearance -> Theme Options for details of the correct dimensions, and upload your image. Copy the URL of the uploaded image, go back into Appearance -> Theme Options and paste it in the appropriate box. When you save your options, the header image should have been updated.
