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 share a link to Facebook, the image associated with the link can be displayed in a number of ways. Again, all depends on the image size (pixel width and height) and shape (orientation). Images previews for shared links are scaled to fill a box of 470 pixels wide by 246 pixels tall.
