Given thousands of named strains, I doubt it... I keep over 40 DIFFERENT strains in mother form and of those, few are different-looking enough to pick out in a lineup, and that is knowing what the list of potential suspects actually contains. And yes, I have an eye for strains. It's easier to tell the actual plants apart than a finished, dried, packaged bud that retains very little of the uniqueness it had while still on the plant.
You happen to know what is going around your area. If you've got like 6 to pick from, yeah okay you can probably pick out which is WW. But there are a hlaf dozen 'white' strains I could list, and a LOT of stuff looks similar to OG Kush. Whatever, I'm saying that there's no way in hell that you can look at a picture of a dried bud on the internet and say 'doood that's X'.
