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 upload a square image to share, it will be 470 pixels square, the maximum allowable size in a Facebook feed. Thisâll be the case no matter what size square you upload, be it an 800 x 800 image or a 400 x 400 image (the smaller images might appear a bit blurry when they are sized up to 470 pixels square).
