Earlier this year we added the ability to import photos into SIMs. This is an addition to the write back we could already do for pupils, staff, contacts and SIMs users (https://blog.salamandersoft.co.uk/index.php/2015/11/salamander-active-directory-can-write-back-to-sims-emails-udfs-etc/).
If this is something that you would like to add to your installation please send an email to support.
