You don't have to worry about Bitcoin and quantum computers for at least the next 10 years :)
We are still a long way from QC being able to even begin to pose a threat to Bitcoin.
And if it does happen at some point, a soft fork can be used to switch to a quantum-safe address format :)
Regarding your question about the image: You should have clicked away the image of the link you inserted. You can only insert either an image or a link with an image (if you can call it that).
