Save as: TIFF black/white bitmap with a resolution of 720 dpi (small molecules) to 240 dpi (large molecules) (in ChemDraw under the Options button in the Save as TIFF dialog). ChemDraw / ChemBioDraw 11 (2007) cannot save black and white TIFF images. Therefore, save as a 1200 dpi greyscale TIFF image and decrease the color depth to 2 bit (black ...
Images composed of simple shapes, lines, and letters such as those below should be recreated using vector graphics as an SVG file. These have a number of advantages, such as making it easier for subsequent editors to edit them, enabling arbitrary scaling at high quality, and sharp high-resolution renderings for print versions.
It is advised to check the references for photos of reaction results. [1] Reagent testers might show the colour of the desired substance while not showing a different colour for a more dangerous additive. [ 2 ]

Often, SVG editors will specify unnecessary parameters (e.g. stroke:none;stroke-width:1px; — the stroke-width parameter is superfluous if stroke is "none") which can be removed with a search-and-replace. Often, SVG editors specify default parameters (e.g. fill-opacity:1;) which can also be removed.
Have a look at Category:Chemistry pages needing pictures; pages transcluding {{Chemical drawing needed}} automatically categorises pages which have a the request template into this category (replace incorrect drawings with this template), as does the parameter needs-picture=yes in the project banners {} or {}.
Prior to the use of computer graphics in representing molecular structure, Robert Corey and Linus Pauling developed a system for representing atoms or groups of atoms from hard wood on a scale of 1 inch = 1 angstrom connected by a clamping device to maintain the molecular configuration. [4]
