"Allowed File Types" Image filenames with uppercase extension won't render

[wykananda]

If an image file is uploaded with a capitalized extension (ie. image.JPG image.PNG), the image will not render (regardless of the casing of the setting in the "Allowed FileTypes" box).

Good find.

There are more problems with uppercase filetypes. IE does not show images with uppercase jpg extensions. (.JPG / .JPEG). Quick fix is updating the database et_attachment filename table:

UPDATE `et_attachment` SET `filename` = REPLACE(`filename`, "JPG", "jpg") WHERE RIGHT(`filename`, 3) = "JPG";

Ideally we should change the filename to lowercase before/when uploading
