Problems Creating Banner

I’ve spent countless hours trying to convert several of the jpgs and pngs on my computer into banners using the on-line image resizing program “IMGonline.com.ua” at Resize image in pixels online - IMG online.

When I put the resulting image into my page, the image always looks fine. However, when I preview my page, or view it as people would see it, the top of the image is always cut off, no matter what I set its width and height to in pixels.

As I have no problem putting images into posts, I was wondering if somebody here can tell me why I can’t convert an image on my computer into a banner.

Thanks very much in advance.

If so, this is not the place to ask about it. Asking it at Patreon Discord or opening a support ticket at patreon.com may be better.
