Updates to Lessons, Reviews, and Extra Study

Thanks for the heads up. This is actually by design to help visually impaired people. We added this so that screen readers could interpret the characters correctly. We did consider the fact that it would give away the meaning, but the number of subjects that use images are small so we didn’t think it would be to much of a problem for non-visually impaired people. If more people do have an issue with it, we could preload the images which would reduce the load time, but that is an optimisation for another day.
