Script deletes used images if file extensions are capitals e.g. .JPG

[claremacrae]

This plugin deletes images that are linked.

I was able to restore them from version control, so I'm OK... but still...

Environment

• macOS 10.15.7
• Obsidian v0.12.19
• Clear Unused Images 1.0.3

Demonstration

Here are some existing links to images:

When I run "Clear unused images" I get this output, showing me that all those linked images were deleted:

Seems to be caused by this RegExp not matching case insensitively (and your images are .JPG instead of .jpg)

Line 6 in 6ebc6bd

const imageRegex = /.*(jpe?g|png|gif|svg|bmp)/;

Thanks!

I'm not sure... I'm experimenting with it some more - I just tried it out with this:

![[20211102074439.PNG]]

[[20211102074454.PNG]]

Where the images are .png - and got "no files deleted"

(I am on a Mac, where the filesystem is case-insensitive)

Confirmed.... If the case of the file extension is not all-lower on disc, then the files are removed - even if they are used, and used with consistent extensions in the markdown.

Thank you for working out the cause...

I just released a version, in which the check for image extension is not case sensitive.
@claremacrae Let me know if the issue still persists.
Thanks!

Thanks very much! And thanks to @lishid for spotting the cause...

I've done the following tests - all successful: 🎉

1. Checked that it no longer deletes used .PNG and other capitalised extensions
2. Checked that it does delete unused .PNG files
