In the content of a paper, words, tables and pictures are relatively independent concepts. If you contribute to sci journals, the pictures of the papers will not be uploaded separately, which will bring trouble to journal editors, delay the publication time of the papers and affect the smooth publication of the papers.
Authors contribute to sci journals, and journal editors will rearrange your papers. Graphics should be inserted into the text one by one in the form of pictures, and then the caption corresponding to each picture should be added. If the pictures of your paper are not uploaded separately, but uploaded together with the text of the paper, the editor needs to save the graphics inserted into word as pictures one by one, and then insert them into the rearranged text of the paper, which is really troublesome! Therefore, the papers in sci journals should be uploaded separately. Anything uploaded incorrectly will bring "no pictures" to journal editors and affect the smooth publication of papers.
