Accept images with capitalized extensions.

[miggazElquez]

When using the "Attach pictures/audio/video" button in the "Browse" window, files with a capitalized extension (e.g. image.JPG) aren't selectable.

Add a variable pics_uppercase with the extensions in upper case to be used when selecting a media.

I modified only the places where pics (the list of supported extensions) was used with the funciton "getFile": on the other places, the text is converted to lowercase before comparing.

I did only handle the pictures, because I don't think I ever saw a audio file with a capitalized extension, while for pictures it is very common (1/3 of the pictures I downloaded for my deck where ".JPG").

This is not a problem on Windows at least. I wonder if this is file-manager-specific or a Qt bug? What's your OS/file manager?

[miggazElquez]

I think on windows the file system is case insensitive, so it make sense.
I'm on linux/gnome.

I thought that this worked for me but after testing it now, I can confirm that the gnome file manager (nautilus) doesn't display file extensions that are upper case (edit: I should clarify: it does display them, but not if used with ankis media filter when trying to open the file); which means test.JPG cannot be selected, but test.jpg can be selected.

(though I have very rarely seen upper case file extensions anyways; I thought that's common only on windows)

I can confirm your solution works. But I'm wondering if its better to add the uppercase versions directly to pics = ("jpg", "jpeg", "png", "gif", "svg", "webp", "ico", "avif").

That way, there would be less computations (potentially faster code) and it's clear at a glance that upper case and lower case extensions are being handeled.

Like this:

pics = (
    "jpg", "JPG",
    "jpeg", "JPEG",
    "png", "PNG",
    "gif", "GIF",
    "svg", "SVG",
    "webp", "WEBP",
    "ico", "ICO",
    "avif", "AVIF"
)

And for consistency reasons, we probably should do the same for the audio files as well.

They are quite frequent on the internet, I found this problem while downloading pictures from wikipedia, I think something around 1/4 or 1/3 of them are upper case.

I can confirm your solution works. But I'm wondering if its better to add the uppercase versions directly to pics = ("jpg", "jpeg", "png", "gif", "svg", "webp", "ico", "avif").

I was wondering about it too, I will change it that way if you prefer.

I think this is fine for now. For consistency, maybe it makes sense to handle this in getFile() in the future, especially since the Python editor will be deprecated in #4029
