This image shows some kind of formula that could be converted to
TeX. Storing formulas as images makes it harder to change them. TeX also helps making sure that they all use the same font and size. A replacement has been proposed:
In your article, replace the image with:
<chem>H{:}\overset{\displaystyle H }{\underset{ \displaystyle \ddot{H} }{\ddot{C} } }{:}H</chem>
This image of a simple structural formula is ineligible for
copyright and therefore in the public domain, because it consists entirely of information that is common property and contains no original authorship.
