Yet another ... after the fact contract dispute regarding deliverables.
Contract (verbal) dispute over $1.25 / image
Since she obviously feels you\'ve dealt with her unfairly .... you could offer (in writing) to provide her restitution via a full refund of the $26, nullify the (disputed) verbal contract, take down the pics (no use for either party) and destroy the files (no future use) as a means of eradicating the dispute.
I say this not to suggest it is the best appoach to resolving this, but more as presenting an option to her that she might realize that there is a better option regarding how you two can / should work together to resolve this one, rather than her trying to force your hand (vice versa) ... basically the \"alternate proposal\" method.
If she were to go \"all legal\" on you, what could she \"force you to do\" without the benefit of a written contract ... small claims court for a refund, letter to your ISP requiring removal, cease & desist. She\'s got no teeth other than to restore things back to \"zilch\" ... hence the refund/nullify offer and skip the legal route ... if that\'s what she really wants.
Again, not the best option ... but sometimes offering up a lesser option can get someone to realize that they actually have a better options that they were previously dismissing.
