I thought I'd post my blurb on responding to homework questions which violate site policy.
If you see any, just post this as a comment, usually the user will edit their question.
Hi, Welcome to Economics SE! we have a policy regarding homework questions where we require that you show some work before an answer is provided. More on this topic here:
https://economics.meta.stackexchange.com/questions/1465/economics-se-policy-on-homework-questions
the user in question shows his work using only images an appropriate response is:
Hi, Welcome to Economics SE! we have a policy regarding homework questions where users must demonstrate effort using text, markdown syntax and/or images space provided in the text of his question submission for the site. Using only images as proof of work is insufficient. for more details see:

If the community helps, we can improve question quality without newer users undergrad students.
If anyone has a better blurb or idea, please post.
