Test Embeded Image
Enter the URL of the Image:
Image:
Background color: other color: # (hex)
Referrer will be passed. You can choose to not pass referrer to a remote server.
Disable referrer: http://savanttools.com/testimg.asp?referrer=no
Link with image: http://savanttools.com/testimg.asp?img=some_image_url
QUICK TIPS:
Quickly test if the image can be hot linked.
Quickly test if the image has any transparency.
Quickly test how a transparent image or icon looks on a color background.
Quickly test a data URI image. Example: data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAAUAAAA...
Details & Explanation
This webpage is a utility designed for web developers and designers to troubleshoot and preview image rendering within a web context. It functions as an isolated environment for testing various image display properties prior to deployment on a production site.
The utility's primary function is to facilitate the isolation and testing of specific image rendering issues and design considerations.
1. Hotlinking and Referrer Testing
- Test Hotlinking: This confirms if an image hosted on a remote server can be directly embedded (hotlinked) on a webpage. Since some servers block direct linking, this provides an immediate validation.
- Referrer Control: The option to disable the referrer header allows for testing if the remote image server restricts access based on the request origin. This aids in diagnosing a common cause of rendering failure when attempting to hotlink.
2. Transparency and Background Preview
- Transparency Check: Users can verify the intended transparency of an image, particularly for PNG or GIF formats. This addresses cases where incorrect saving may result in a solid background (e.g., white or black) instead of transparency.
- Colored Background Preview: This function supports design verification. By specifying a background color (via a hex code or selection), users can accurately preview how a transparent image or icon will render against a specific webpage background color. This assists in preventing visual conflicts between image borders and background colors.
3. Data URI Testing
- Data URI Image Testing: This allows developers to validate Data URI schemes for images. Data URIs embed image data directly into HTML/CSS code as a base64 string, thereby eliminating an HTTP request. Testing a Data URI string here ensures correct formatting and rendering before implementation in production code. This is applicable for small icons or performance optimization.
In summary, this webpage focuses on validating image URLs, testing server permissions, and previewing design aesthetics related to image display. This consolidated environment reduces the need for repeated uploads and tests on a full development server.
