I'm reasonably, reasonably sure I should probably come up with actual uniform thumbnails for my stories. Or should I keep doing the generic 'slap whatever I can find on it' thing I've been doing? I've seen people do both, but I'm slightly worried uniform thumbnails could come across as tacky or annoying, especially as the 'title and content within at a glance' thing is usually pretty common (and mine would certainly be less high quality than people who know what they're doing). On the other hand, I doubt that what I've been doing is particularly professional or impressive, either.
I am conflicted! Thus, I throw my questions at you, internet vore fellows. What do you guys think?
