With metaPost, you can configure your image path using tokens, however there is a possible issue with the use of a localized friendly name for your module.  If, for example, you have changed the name of the News Articles module to something like туцқғфкешсдуқ, then you cannot use the [Provider] token to configure the image path.  Here are the tokens that can be used:

[User],[Provider],[Year],[Month],[Day], and [FlattenedFilePath] or [FolderFilePath], where [FlattenedFilePath] and [FolderFilePath] are requried.  [FlattenedFilePath] simply removes the forward slashes from the folder hierarchy returned by some clients such as Windows Live Writer.

Since the provider key is the friendly name of your module and since DNN currently doesn't support Unicode characters stored in the image path, you'll need to avoid an image path like the following:

images/[User]/[Provider]/[FlattenedFilePath].

Instead use something more like this:

images/[User]/metaPost/[FlattenedFilePath]

if you are using the Community Edition and like this:

images/[User]/newsarticles/[FlattenedFilePath]

if you are using the Professional Edition where an image path can be configured for each provider.
