Hi, everything seems to work fine, although i cannot find any options to change the facebook feeds image size, at the moment my posts are huge, i would like to better resize them smaller so that the avarage size fits better in the page.
How can i do this?

Hi Alfo! Thank you for posting your request!

If you are displaying a group feed, then Timeline must be selected as your feed content type. There's a Width option upon its settings, which will help you control the feed width, and thus the with of photos in it.

But if you are using a page, for example, you can select Specific content type, where you are able to set Image thumbnail dimensions.

Thank you! Have a wonderful day!
