Category-specific confirmation email image #9
Description
If we collected a bunch of category-specific GIPHY images, we could tailor the confirmation email to match the activity category that was submitted. This would increase the number of different prize opportunities we have available (e.g., the points winner in each category for a given week/month could choose the GIPHY for the following week/month).
I'd thought about placing these into a new column of the Activity Categories sheet, but that would force us to run updateActivityCategories() just to change one of the images. That's an awkward constraint, since this sheet might be in a half-revised state. Perhaps this is reason enough to keep two instances of this sheet: one active plus another draft still under development?
