问题
In the ADB2C user registration flow you have an picture on the left & the form on the right. Is there an easy way to change the picture on the left? I don't want to redesign the whole page.

Full customization which includes your own HTML/CSS is available for all the Azure AD B2C user flows including the "sign-up or sign-in policies" which offers a combined - registration and login - policy.
The "sign-in" policy type is the only one that offers the ability to customize via the "company branding" feature which needs only a picture upload.
All other flows require upload of HTML/CSS content. A template is available. Full customization is documented here: https://docs.microsoft.com/en-us/azure/active-directory-b2c/active-directory-b2c-reference-ui-customization
Page UI Customization is under Policy->Edit policy->Page UI Customization->Select page->provide source URI

Update
How you get to Company Branding has changed, see this SO Answer.

Yes. Go to Users and Groups -> Company Branding -> Edit -> Sign-in page background image.
I couldn't find an official documentation on docs.microsoft.com/azure/active-directory-b2c to reference, unfortunately.
