Usually, the font size and format of the pictures cited in the paper will give clear requirements. If there is, we just need to set it according to the requirements, but sometimes the professor will not explicitly give the setting requirements. If this is the case, we only need to make the font size format of the picture according to the format requirements of the paper body. At present, the most common format is APA, and the font format is TimesNewRoman. The size of 12 is 2.0, but it should be noted that the picture should be centered, that is, it should be displayed in the middle of the paper, which is different from the text quotation.
