Change Image/Icon Across Sight

The easiest way would be to connect via FTP or File Manager in your hosting account and upload a new image with the same name into the folder where the current image is – that would override the image and swap it out everywhere it displays, without having to touch any code or manually update page images.

Hope that helps.

Doing it by overwriting the file sounds good at first, but it would not update the other image sizes that are generated and the metadata for each. And especially if it’s a different size or file type (png or jpg), it would not be a good way.

If the image or icon in throughout the whole site as per the OP’s description, then I would assume it’s like a logo, banner or icon in a sidebar or something and not a featured image in just a post or page which would use multiple sizes.

My solution works if it’s a like-for-like image you just want to swap on every page. If it’s a featured image in a post, then you would need to manually replace it for each post/page editor in order to create/crop the different sized images used in the theme.

Thanks for all the replies! All of you helped me get out of the mental box that I had put myself into by overthinking it, the images in question are all thumbnails, so there would not be any need for fancy foot work to cause the change from occurring, so I am gonna give it a shot with one to see what happens. THANKS for the leads y’all!!
