Image Preview

Display thumbnail previews of selected images before uploading. Enable with asp-thumbnails="true". Thumbnails are generated on the client side using the browser's native image APIs, so no server round-trip is required.

What you should see: a thumbnail for every selected image, generated locally before upload. Accepts the common image types up to 10 MB; non-images are refused.
