I'm mulling this over as I work on an inquiry to see if dev time can be spent on this.
The question of what the homepage indicator should look like is the easy part. Here's the hard part: should there be an indicator like this for every post that has a photo in it? I think not. I think the goal here is to promote questions that are about photographs, as opposed to about gear or software.
It's been suggested that we have some sort of Markdown syntax that denotes "this is the image to use as a thumbnail" in a question that has multiple images. I'd take it a step further: that syntax should be used to denote "this is a photograph I made and not a screenshot or random image search shot".
It's my hunch that using thumbnails won't fly very far because of the performance implications, but I will look into it. (It's also my opinion that a text or graphical indicator would be preferable over a thumbnail, but that's probably just my bias toward keeping a clean homepage coming through. I'll still look into the thumbnail thing.)
So, in short, we'd have:
- A piece of Markdown syntax denoting "this is the photograph my question is about"
- An indicator on the homepage displaying either a thumbnail of that photograph or some other "has image" notation
This sounds good, but it's very hard to enforce this programmatically. There's really no way to prevent people from putting the "this is my cool special image" tag on a snapshot of their DSLR settings window. It could very easily turn into an "unofficial bounty" - a free way to get more attention on your run-of-the-mill "how does my lens work" question without having to wait two days and spend fifty rep on a bounty. We'd need buy-in from moderators and editors to watch this feature carefully and make sure that it's truly only being used on questions about photographs.
Does this mean we shouldn't do it? Maybe. Probably not. But it's certainly something this community needs a clear stance on before we can proceed.
