Auto set first photos of a post as feature picture

Hey there,

After installing the theme, i found out that all my posts ( @700 ) do not have the feature picture from the last theme.
How can i set all the first pictures of the posts as feature picture? or is there any other solution?

Thanks in advance.

The solution we use is called Auto Post Thumbnail PRO which is also available super cheap via Envato/Themeforest.

It will automatically make first image in post the featured image, and also works if it’s a video only post, and you can set a default image, and regenerate (check memory setting, or it will just stop about about 300 items). Works great.
