I'm having problems using the Wordpress native gallery feature with Thematic & child themes. When I insert the gallery using a 3 column layout, it will end up only displaying 2 columns, bumping the third image for a given row down to the next line by itself. It will then start over with the next row doing the same thing. You can see an example of a 3 column gallery here:
The same thing happens with a 4 column gallery, only it leaves 3 images on the first row and bumps the 4th. No matter how many columns there are, it always keeps all but the last image on one row. Here's an example using a 4 column gallery:
I switched back to the default Twenty Ten theme that comes with Wordpress, which displays the gallery exactly as it's supposed to so the gallery code itself works properly.
How can I fix this?
