Having read Bart Koopman's post, "Having fun with Experience Manager, Page Regions and Widgets," I want to recommend Multimedia Components to model promotional content types for things a business might call:
Since these can have a 1:1 relationship between image and its text (image "drives" the text), this could make it easier for authors in Experience Manager as well with Content Manager Preview with fewer authoring steps and less items (and maybe even code) to manage.
I can imagine two concerns for implementation:
Authors can add a Multimedia with a matching template to a page in the Content Manager Explorer or Experience Manager. Component and binary items are available via the Content Delivery API. Templates can reference both the binary and the Multimedia metadata, which can include text. And Translation Manager can handle the metadata as well, right?
I wouldn't recommend images-as-the-Content Type itself except when the image and text are closely related and the text might only change for translation.
To confirm, are there reasons or trade-offs why we shouldn't use images for promotional content types with their text as metadata?
Down vote or suggest changes to the question if this is a bit too open, but considering this is "backwards" of the typical text Component linking to a binary, I'd appreciate thoughts on why we don't see this more (yet) or trade-offs to consider.
