i use same metadata for similar sets
captioning images is the most time-consuming part of submitting microstock - i have thousands of images needing metadata, so if i can do multiple images at once, i can submit more. and at the $ we receive it isnt worth the time to tweak each image without knowing if any of them will sell
trying to game the system without knowing the rules of the game is a losing strategy, especially when each agent has its own secret rules
