Some JPEGs don't convert

[chrispratt-tonyyeb]

We have a number of examples where JPEGs uploaded from mostly Samsung phones don't convert. From what we've found it seems that they create the images using HEIC and that the export to JPG option does not always creating full compatible JPG images.

By opening the original image in Paint and saving again, the image then can be uploaded and gets converted. Attached are two images (original.jpg which does not convert and new.jpg which is the same image resaved in Paint which will convert). It looks like most of the difference between the two is in the colorspace - the Paint saved image has noticablly fewer colors.

Is there anything that can be done to handle the original image?
