Description
I have an image field like this:
logo_help_text = "Company Logo" logo = models.ImageField(upload_to='logos/', blank=True, null=True, help_text=logo_help_text)
I can upload lots of different images, in Django Admin to this field without issue. The particular image I was trying to upload had no problems being uploaded, but the image contained a logo with dark letters, and my website background color was dark, so it looked bad. All I did was use Gimp 2.10.4 (MacOS) to change the color of the company name text in the logo to a lighter color, and export the PNG.
According to linux's 'file' tool, both the source logo, and the resulting logo are identified exactly the same:
test.png: PNG image data, 1280 x 403, 8-bit/color RGBA, non-interlaced
For some reason, when I try to upload the resulting PNG, Django admin tells me "Upload a valid image. The file you uploaded was either not an image or a corrupted image.".
Image file that can't be uploaded attached.
