BMPs result in "file failed to upload" error w/ Advanced Editor

[JulieVanilla]

Attempting to upload a BMP file with the Advanced Editor, even when it's specifically whitelisted, results in receiving a "file failed to upload" error.

Expected result: BMP is attached without issue.

Should have sprinted label.

Did you try both the "select file" and drag & drop?

[JulieVanilla]

Confirmed that neither select file nor drag & drop works. Both throw the file failed to upload error.

There's nothing currently in Vanilla for handling bitmap uploads. This is because PHP doesn't have the native ability to handle bitmap files. It supports WBMP (wireless bitmaps), but not the BMP we all know and love. I don't think there's any real way to make this happen without bringing in a third-party image library or investing significant time into making our own.

I vote we just leave BMPs in the past, where they belong.

@initvector I don't think the goal here is to allow them as image uploads that embed or render, but rather to just make them an attachment, like a ZIP or PDF.

[JulieVanilla]

Confirming the desired action is to allow them to be attached, not necessarily rendered.

[initvector]

That makes perfect sense to me! PR for that very thing is pending review.
