[feature] Enable Image link & alt rendering just like anchor rendering

**Version and OS**
0.40.0.4 via Docker-compose on Linux

**Is your feature request related to a problem? Please describe.**
Changes in the image links/alt are not detected.

**Describe the solution you'd like**
Just like we render anchor text by enabling in the global filter, if we can add an option to render img src link & alt text then that will serve the purpose.

**Describe the use-case and give concrete real-world examples**
There are many websites that have Images that don't have links or text associated with them these image changes are never detected but if we render the alt & img scr tag url then the problem can be solved.

**Additional context**
If this can be limited to per watch filter instead of global filter then this would be even better.

Start by tracing the global filter behavior that currently renders anchor text, then inspect how image links and alt text are handled during change detection. Confirm whether the option should be global or per watch, and verify that changes to image URLs and alt text are detected without associated links or visible text.
