JPEG compression percentage column

[user123]

I would like to suggest a feature that checks a jpeg/jpg file compression percentages (quality) and shows them in a column. Currently it seems it's impossible to do that. There is a 'Compression' column, but for me it's empty for jpeg images, or just shows Uncompressed or LZW for some.

Here for example a jpeg file is opened in irfanview and its quality is 84%:

test1.png (204.96 KiB) Viewed 1107 times

[void]

I have put on my TODO list to add a jpeg quality property.

Thank you for the suggestion.
