Regex Tester & Validator

This regex matches HTML image tags and isolates the URL within their `src` attribute. It looks for the `<img` tag, locates the `src` property, and captures valid URL characters enclosed in either single or double quotes. It is highly useful for web scraping, parsing HTML content, and validating or migrating image assets. The regex utilizes global, multiline, and case-insensitive flags for robust searching across entire documents.
