Contact images broken when file extension is capitalised (e.g ..JPG) "Supplied mime-type does not match file extension"
We have a number of existing contact images that are now displayed as broken links. These images all have uppercase file extensions ".JPG". This error is displayed: "Supplied mime-type does not match file extension".
This behaviour commenced with 5.13.4 and is still present in 5.14.0.
This error message looks to have been introduced commit b5230444 in
Trying to debug this, in
run() for one of my broken images with extension .JPG:
JPG in uppercase
['0' => 'jpeg', '1' => 'jpg', '2' => 'jpe'] all in lowercase.
What is puzzling me is that I cannot reproduce this on dmaster but yet I do still see the problem when I test locally with the master code and I can't see any relevant changes. I'm using Joomla 3.9.8 so it could be CMS-dependent but it's not immediately obvious how.
