Hello @Jovix. Thanks for coming into the Community with your question. You are correct in saying that the maximum width of an image being up loaded into the library is 800px and any image larger than that would be reduced in size. The reason why we allow larger images to be used on an event landing page is because it is created as a website and not as an email. If you did want a image larger than 800 pixels to appear on your landing page, you would want to host the image elsewhere and then insert it as a URL. Hope this helps!
