text: Jim: there's a minimum of 10 images per user but it's not the limit
  Jim: you can upload more if you want to
  Carol: and they will take all of them?
  Jim: I'm not sure
  Jim: because you can upload like 20 or 30 or even more
  Jim: but you have to tag 10 of them as favourite
  Jim: so maybe they just pick the tagged ones for the first stage
  Carol: I'm not sure if I can find ten...
  Carol: I mean I have more obviously but you know...
  Carol: not sure about the quality
  Carol: <file_photo>
  Carol: <file_photo>
  Jim: these are really good ones
  Carol: thanks
  Carol: I mean these 2 are very similar and I'm not sure which one I should choose
  Jim: I'd go for the first one then
  Carol: ok :)
target: Carol has to upload at least 10 photos but she's not sure if she finds as much as 10 of good quality.
