I just decided to risk eternal exile from iPad world by uploading an Avatar to my profile on this Forum (potentially ghastly sight). I noted the recommendation that the image be at least 200x200 px, and I tried to upload an image that is 216x220 px. My Avatar was rejected because it exceeded the limit of 50 KB (it's 108 KB). It strikes me that you can't have both! What's the secret here?
