Visualization and download of images, audio, video, ANYTHING, from websites by detecting direct HTTP URI scheme addresses to files, with the specified extensions, contained in the website source code.

To save storage, energy, time, and bandwidth, I removed the "greedy download" mechanic. Now the user can choose what files to open in the browser for viewing or downloading. This also reduces the probability of getting blocked by a server.

I didn't use "Linkify" because scrolling becomes a pain with so many links. I put a Choice Dialog for easier navigation without accidental opening of links.

This flow can work with local files, even if these files aren't HTML, by replacing the Input Dialog by File Picker and HTTP Request by File Read. It can also work with files on a FTP server rather than HTTP server, by replacing HTTP Request with FTP Download.

Any suggestions to make the regex better are welcome.

Note: this is case-sensitive. I know how to make the entire regex case-insensitive (using the "(?i)" prefix), but ONLY the extensions should be case-insensitive. I don't know how to make that part case-insensitive
