How to avoid emails with a picture from getting into google spam?

Question

Google

Hello, this is the situation. There is a letter with a picture that I send to a client and everything is fine on all mail services, except Google
I use Yandex PDD, it automatically signs DKIM and RTF
But Google doesn’t like DKIM for some reason -

mail._domainkey	TXT

v=DKIM1; k=rsa; t=s; p=MIGfMA0GCSqGSIb3DQEBAQUAA4GNADCBiQKBgQDE2KCXq3uBMmPfZZI5d4uXu8OMvOJ8TxupL0DQgT7wLy79w5xo4ToJ8TuRERIjP2rWiRDPS97gjXLB9LbqtGd0pbgart4Vdif9jH8acU6vXTXJ7Ej6V5aci6LqmdllWHfLXBj02+bod7b6uKRrO8qGlNLmlQ0fpsU2UK+Y8WNxtwIDAQAB

He does not like SPF, although he also has it, that's what Google writes

Decision	domain owner discourages use of this host
Record	v=spf1 redirect=_spf.yandex.net

He also complains that - DMARC record is not configured
As for, PTR - @ record is a link to a domain, and PTR is a link to hosting
Google exchangers not found. Check the smart host setup.
What we have? And we have a complete random, tested 10 mailboxes, including those that have just registered, in a completely random way, letters end up in Promotions, then Inbox, then Spam
I would like all letters to go to Inbox, to the edge in Promotions
I already spent a lot of time on this, can someone suggest the right way?
What is noteworthy is that if you cut out all the pictures, leave only the body and write the text, everything is ok. That is, I somehow need to recognize my letter with pictures as not spam, or this is impossible. Removing the pictures, would that be the solution? Someone mb tested ...

GMail doesn't like external images, only showing them on emails from trusted sources. Use inline pictures.
