The existing JPEG detection logic is too restrictive because it checks for the file header "FF D8 FF E0", which only matches JFIF-type JPEG images... Meanwhile EXIF JPEG images are more common these days.
For reference:
FF D8 = JPEG SOI (Start of Image) header
FF-D8-FF-E0 = JFIF
FF-D8-FF-E1 = EXIF
FF-D8-FF-E2 = CIFF
FF-D8-FF-E8 = SPIFF
As you can see checking for the SOI and then FF matches all extent types of JPEG images. \o/
