Hi,
That’s not possible with the logic of Tiled Galleries. If all of the images are roughly the same size, the math would probably work out to be one column in width, but there isn’t a way to manually set that.
Thanks!
No, that’s whats happening by default. (See the link: http://rhodycigar.com/rhody-pics/) I’m not sure what’s causing it.
Ah, sorry. I misunderstood your original post.
Looking at the error console for your site, I think your theme has a miscoding that is leading the browser to stop executing Javascript, which is required for the Tiled Galleries to work as expected.

I would suggest switching to a default theme (one of the Twenty-somethings, Twenty Fourteen, Twenty Twelve, etc) and seeing if it still doesn’t work.
If it works, then most likely it is your theme causing a conflict that is preventing it from working. Contacting the theme author to look into the source of that error would most likely resolve this (as well as other wonky things you may encounter that rely on Javascript).
Thanks!
