So I just started messing around with Tumble to drive some traffic to my site. One problem I'm having is the picture size. I upload the full size pic (usually 300x300) and post it. When I go to view it in the dashboard it's really small and when I click it it will enlarge. Why is my picture so small when the people I follow have full sized pictures in the dashboard? I've done some searching but can't really find an answer. I am thinking it's because of my theme, because on my blog they are smaller as well. Any ideas?
