If you want to display high resolution web images on the new iPad, you need to use progressive JPEGs, notes Duncan Davidson.
Earlier this week we reported on a Tom's Hardware finding that mobile Safari downsampled web images counteracting the amazing Retina Display on the new iPad.
After examining the situation closely, users found that progressive JPEGs are not downsampled and display in full quality.
A progressive JPEG divides the image file into a series of scans. The first scan shows the image at a very low quality setting, and subsequent scans improve the quality. Each scan adds to the data already present, so the total size of the image isn't that much different.
As you view a progressive JPEG you may notice that initially its of low quality but the longer you wait the better quality it gets.
