Generally, you need to upload vector high-definition pictures separately, and typesetting has little to do with it. But if you want to have better quality, you need to scale the picture to A4 page width to make the text clear. Use font size 6 or above to ensure clarity, and then the picture accuracy requires more than 300dpi. Of course, in addition to accuracy, the font size should be the same as the font size of the picture name below. If the picture is too big or there is too much text, it can be reduced appropriately.
