Definition of Theme. As a literary device, theme is the central topic or idea explored in a text.
I donât know if it has changed, but as for the Carousel ads, Facebook recommends 1800Ã1800 when i create a new ad. Hi Jon, I was previously able to replace the 470Ã246 thumbnail pulled from websites with an uploaded image on facebook.
If you'd like your Facebook ads to be eligible to show in all of the different formats, including the desktop News Feed, mobile News Feed and the right column, then you should use the recommended ad image size for your objective.
