I was browsing on the original iPad. For some reason, certain PDFs seem to stress it out when rendering and it really lags. It also did not correctly display the SVG link.
So all I was left with was the JPG link which was unfortunate because of the lossy compression which makes the finer details slightly blurred.
A PNG would have been perfect and I noticed that all other languages had a link to a PNG but english.
I was browsing on an iPad 2 in Chrome and had similar problems. SVG displayed as text, PDF and JPG were blurry and wouldn't zoom correctly. Once I got on my laptop the SVG still displayed as text but the PDF and JPG were perfectly clear. Still not sure why the others are PNGs and the english version is JPG; clearly PNG is better suited.
