Minor Questions on Supervisa application

[Carmageddon]

I am in the process of preparing the application itself for my In-Law.
I got several clarification questions, please, if any of you able to answer:

1. On online submission, a photo is required, correct? even though she is from a country where she will need to give biometrics. I am submitting online, there is no photo validator tool, the specs are available only for printed photos. Do I just upload the one the photographer made, and hope for the best?
2. One section on the Checklist says to add Purpose of Travel (although that shows under TRV section), and then under Supervisa section, it say A Letter of Invitation. Do I need both? I only got sample formats for the second, not the first... So far I could not find any samples of the first, googling in relation to super visa applications.
3. The very same Purpose of Travel, as well as few more, have a note saying: "Refer to the responsible visa office for your region.". Is there some information online, without contacting them?
   Asking because, when the in-law went into the embassy, she claims she has been told that she should be submitting her own bank account records, etc.. even though no official documents anywhere show that, as far as I can see, so I am reluctant to rely on verbal advice given to someone else by god knows whom.
4. Another similar note for additional documents says "Refer to the visa specific instructions for your region" - I was not able to find that.. anyone?

PS: She is from Moldova


Thanks!

Anyone?
I could still use a Purpose of Travel sample, but my main doubt - is should I specify 1 year as visit period? Or is that bad thing to do? even though we'd be covering all expenses...
