I have that 'Catching Elephant' on my tumblr as my theme, and I tried to make the photos a bit larger by editing the html, but then the quality of the pictures turned really bad. And they're not usually low quality photos, they're taken with a Nikon camera, and the pixels are usually around 3800x2800 (ca), which is why I don't understand why they look so bad now, just because I enlarged them a bit. Please help, it'd be very much appreciated!
