SITE GROUND Hosting Issues/ IMAGES

My host – site ground has had too many issues recently, spammy emails, bot attacks, site downtime,,, and have been very rude to me recently when I have sought to have some simple direction on server side set up WP-Rocket that I am planning to move on from SG.
I need to transfer my images over to another platform and want to know while I am still with SG and use their SG Optimizer plugin; will it conflict with flying images?

SG as a host has too much inconsistencies in speed metrics and lacks server side performance, so I need to move to another host ASAP; they’re Dynamic Caching is not firing – so I am only able to use static, again another issue I have with them – they want more money to be able to use their basic offer, and after 4 years / the price of their service has gone through the roof. …. If they put me back onto Dynamic caching, which is likely not – will Flying Images work in the meantime? Ive have been working on this website for over 5 weeks and just dont want any more major issues.
