I use ImageResizer.net to create images to dimensions I need dynamically, based on one larger source image. It’s done in a url-like fashion, like so: “www.siteUrl.com/ImagePath/ImageName.jpg?width=90&height=90&crop=auto&quality=90”. This resizes the image to 90×90 pixels, cropping, and setting jpeg quality to 90%.
Will this url be acceptable to og:image , so that when someone likes/links to my content within Facebook it shows a thumbnail of the image inside the og:image property?
Yes this URL accepts og:image and works fine…
I have already used this like this eg.
<meta property="og:image" content="http://www.xyz.com/Handlers/ImageGenerator.ashx?id=de69f1e1-ee64-4bd9-80b8-8546bca4ef45&w=50&h=50" />Here i am using Image handler file and passing image id and image id is saved in my database associated with image path and it works fine on facebook….
