HTML Image Code Generator

Create an HTML Image Tag Online

The HTML Image Code Generator creates an <img> element from the image source, alternative text, and optional dimensions you provide. The preview, HTML output, and C# output update together, so you can inspect the image tag before copying it into a webpage or .NET project.

Create an HTML Image Element in C#

The HTML Code panel above contains the configured <img> markup. The C# Code panel below creates an equivalent element with Aspose.HTML for .NET .

The generated code follows this workflow:

1. Create an HTMLDocument and an HTMLImageElement with Document.CreateElement() .
2. Set Src and Alt, then set Width and Height when dimensions are provided.
3. Add the image to the document body with Node.AppendChild() .
4. Save the completed document as image.html with HTMLDocument.Save() .

Configure the image first, then copy the updated C# code into your .NET project.

HTML Image Code Generator FAQ

1. What should I enter as image alt text?

Describe the image’s content or function in the context of the page. Use an empty alt value for a purely decorative image so assistive technology can ignore it; do not use a filename or repeat nearby text without adding meaning.

2. Why is the image missing from the preview?

Check that the source points to an existing image that the browser can request. A relative path is resolved from the current page URL, while an external server may block the request, require authentication, or prevent hotlinking.

3. Should I specify both image width and height?

Supplying both intrinsic dimensions lets a browser reserve space before the image loads and can reduce layout shifts. Use values that preserve the source image’s aspect ratio; mismatched values can distort the rendered image.

4. Can I use a relative image path instead of a full URL?

Yes. A relative src is resolved against the URL of the HTML document, so choose a path that will be valid where the page is published. Use an absolute HTTP or HTTPS URL when the image is hosted elsewhere.

5. Can I add the generated image to an existing HTML document?

Yes. Open the existing file with new HTMLDocument("input.html"), create and configure the image as shown, append it to the required element, and save the modified document to a new file.
