Option to download Full-Size images

[Bo26fhmC5M]

Is your feature request related to a problem? Please describe.

I need an option to download the href link that the image points to (the full size image) without downloading the image itself that is displayed.

<a href="https://example.com/c3ef05d58.png?type=orig" target="_blank">
<img src="//example.com/c3ef05d58.png" width="832" height="1216" loading="lazy">
</a>

For example, instead of downloading the src link of an img tag surrounded by an a-tag, I want the option to download the href link of the a-tag.

Describe the solution you'd like

It should only work if the 'img-tag src' has the same extension (.PNG) as the 'a-tag href' except for the query part (?type=orig).

<a href="https://example.com/wall/136865783?u=5b4faa1d-6e74-11ef-8dea-a2a958ef638c" target="_blank">
<img src="/static/assets/images/point-pc-x2.png">
</a>

In this case, SingleFile needs to download img-tag src because the extension of 'a-tag href' is not .PNG.

Describe alternatives you've considered (optional)

This issue illustrates well what I am describing here #1595. However, in this particular case, this could be solved by integrating a userscript which would replace the src attribute values before saving the page, see here for more info: https://github.com/gildas-lormeau/SingleFile/wiki/How-to-execute-a-user-script-before-a-page-is-saved
