How we read it: CRMLS prints this Flexmls limit as 3000 x 2000 and ARMLS prints it as 2000 x 3000, so we accept either way round: long side up to 3000, short side up to 2000.

California’s AB 723 also applies to every ad that uses an altered photo, not only the MLS listing. The AB 723 guide quotes the statute and the disclosure generator writes the wording for each place you publish.
