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.
Three standard dimensions: 1  Website click ad: If you are creating an ad that contains a link the ideal image size is 1200 x 627 pixels. 2  Like ad: If you are promoting your page, use the same image size as your Facebook cover photo: 851 x 315 pixels. 3  Event ad: Event ads also use the cover image from your event. The ideal size is 851 x 315 pixels.
