Image title not detected by SEO tool (https://raventools.com/)

Hi,

For my site https://activemarketingplan.com/ we have used this plugin. We put title for each images but title not showing in frontend if I look using firebug.

My main problem is Raven tool for SEO https://activemarketingplan.com/ not finding slide image title and it’s showing error so that.

How can I solve this issue ? Can you please advise ?

Kind Regards,
Habib
