I also have a similar problem, I don't know where is the problem：

I don't know if it's a problem with the excel format or a problem with the code

go version：

1.17.13

Excelize version ID：

v2.7.1

demo:

	reader, err := excelize.OpenReader(file)
	rows, err := reader.GetRows("sheet1")
	picCellCos := []string{"F", "G", "H"}

	for index, row := range rows {
		if index == 0 {
			continue
		}

		// the text in the cell
		id := row[0]

		for _, cos := range picCellCos {
			// but some pics is nil 
			pics, picerr := reader.GetPictures("sheet1", cos+conv.ToString(index+1))
			if picerr == nil {
				for _, pic := range pics {
					picByte := bytes.NewReader(pic.File)
				
					// do something
	
				}
			}
		}
	}

Please tell me where I did wrong, thank you ～～
