Image unknown format

[jobnte]

I'm just trying to add an image file but when I generate the excel an error shows up. (I'm just following the examples)

. There is a one.jpg file in the same directory that the .exe generated by golang.
. I used the command go build

xlsx := excelize.NewFile()
	sheet := "Sheet1"

	xlsx.SetCellValue(sheet, "A2", "Picture")

	errx := xlsx.AddPicture(sheet, "A3", "https://i.imgur.com/sJUvygL.png", "")
	if errx != nil {
		fmt.Println(errx)
	}
	err := xlsx.SaveAs("./testing.xlsx")
```

Thanks for your issue, I have checked metadata of the image by exif.regex.info/exif.cgi, although the file extension is .png, but the encoding type actually is jpeg, so you need to import _ "image/jpeg".

I have been imported

_ "image/gif"
_ "image/jpeg"
_ "image/png"

Please provides Excelize version or commit ID, Golang version you are using. I suggest that fill in the complete necessary information in the issue template when you create a new issue, that's will be saving our time.
