I have this link of a structure of a chemical compound (http://pubchem.ncbi.nlm.nih.gov/image/imgsrv.fcgi?cid=4684&t=l) which I want to convert into a .jpg file. Imgur doesn't accept this link directly probably because it doesn't end in .jpg or .png etc. in my mobile version.
I can't save anything locally. An online way of doing this is what I need. A solution based solely on the browser.
How can I possibly do this conversion?
