Does Creatio purge records from SysImage?

Hello Community,

We have a case where images that we inserted via the Database into SysImage went missing. The steps we followed was to insert records into SysImage directly and later map that image Id to the relevant section. 



Does Creatio automatically purge specific records in the SysImage table under ANY condition? If Yes, what are those conditions? Besides purging, does Creatio also go and update the reference Image Id column in the section?

I vaguely remember from a previous experience that Creatio did purge records based on some condition. Request your assistance.
