Speaking for myself, as a newer member/owner, we had a lot more photos that would have be interesting to consider.. but most all taken with our iPhone and not meeting the quality/pixel requirements.
Going forward, we'll be aware an be able to take a few more shots with our SLR for that higher density requirement.. but, in practice, we only have 1 SLR picture for every 20 iPhone pictures to select from.
I assume there's no way to deal with lower-res images.. so it maybe a matter of putting the requirements and ask out there early in the year.. so people are aware and try to get appropriate images during their season -- not just looking at what they have at the end of the season. Maybe even do a monthly/quarterly outreach .. and keep the visibility and engagement more top of mind during the season.
