They both look blurry compared to the image that I uploaded – something to do with image optimisation? It hasn’t happened elsewhere on the website.
(I realise that it’s a huge file, when I was testing I tried making the image big in order to fix the problem).
I guess this means that the problem is within the StarKid theme, not the BuddyPress plugin?
