The argument against it being that since it is the only content on the page no <section> is needed and that it is conceivable that in the future extra content could be added in between the <div> and the <ul> which is not related to either.

No need if, as you say, this is the only content on the page (+ header
and footer).  <body> is an implicit sectioning root.

> 2) Should the <div> be replaced by <section>? The argument being that this detail-picture is actually the main content of the page and could also include extra information (like a textual description) in the future. The argument against is simply that the <img> is adequately semantic and the <div> is there only for lay-out/scripting.

Without any further context, I'm going to assume that the <div> is
indeed purely a styling/scripting hook.  In that case, it should
remain a <div>.

> 3) Should the <ul> be wrapped in an <aside>? Since it is definitely related to the detail-picture. But see also 5)

Definitely not; it's part of the application.  From your snippet, the
page seems to be built as a picture-app, which means both the image
and the thumbnails work together; neither is tangential to the purpose
of the page like a sidebar would be.

> 4) Should the <ul> be replaced by a <nav>? Argument for it is that clicking on a thumbnail changes (part of) the page and is therefore not a "true" list of items but a form of navigation. The argument against is that it is highly debatable if this constitutes a real form of navigation.

No, it probably shouldn't be a <nav>.  It's possible to argue for it,
but this probably isn't a "primary navigation" for the page.  It's
just part of the application.

> 5) Now stretching a bit, it is conceivable that someone may argue that the thumbnails are actually the main-content and that the detail-picture is nothing more than a detail of part of that content.

Nah, both pieces work together to create the application.  Arguing
that is really esoteric semantic-hacking, and isn't necessary.
