There is a question on meta.drupal.SE, which is similar to the "Community Promotion Ads - 2017" question on this site here.
Here is one of the answers over there (disclosure: it's mine), to recommend softwarerecs.SE for Recommendations related to "Contributed modules for Drupal". For those who want (and are able) to consider doing so, please help me "push" it over there.
And for those of you who are less familiar with drupal.SE, be aware of this:
- Questions like "Is there a (contributed) module to do X?" are considered off topic over there ... most of them get put on hold right away.
- Even though "There is a (contributed) module for it" is like a trademarked phrase in Drupal-space, and a perfectly acceptable answer to mostly any question over there ... go figure.
To get an idea of the challenge for finding an appropriate contributed module for Drupal:
- here is the list of modules to pick from ... right now 36,597 hits ... only.
- here is the list of themes with a similar challenge ... right now 2,413 hits ... only.
More info: Is asking for Drupal modules and/or themes on topic?
PS: I'm not a graphics expert (can you tell?). So anybody who wants to contribute a more shiny image (which fits the dimension criteria), please let me know (eg by posting it as an answer to this meta question here).
