So if you’re producing your own podcast and want to enhance it with your own logo, or just want to embellish some of the tracks that you already have in your MP3 collection with album art, what’s the best way forward? A 300 x 300 pixel image is actually over twice the size of a 200 x 200 image, and will consequently lead to approximately double file sizes. JPEG images of these dimensions will vary in file size (dependant on the compression ratio used and image complexity) from around 10kB to 80kB or so. The picture to the right is sized at 300 x 300 pixels and is 62kB in file size by way of example. The majority of podcasts that include images embedded within them adopt an image size of 300 x 300 pixels. The iPod touch screen is 480 x 320 pixels, more than sufficient to display images of 200 x 200 pixels. The resolution of the iPod nano and iPod classic screens is 320 x 240 pixels. The picture to the right is sized at 200 x 200 pixels by way of example and is 35kB in file size. iTunes currently displays album art as 200 x 200 pixel images.

If on the other hand you add an 80kB album image to every single track in your MP3 collection, let’s say of 1,000 songs, then you’ll need any additional 80MB of storage, which could otherwise hold a further 20 songs or so (another 2 albums). For example, adding an 80kB JPEG image to a single 8MB podcast won’t have a significant effect it’s only a 1% increase in file size. However, this does need to be taken in context. Unfortunately, any additional information that you add to an MP3 file will increase its file size and this is of particular importance when adding images due to their potential size, even with compressed images such as JPEGs. Quite an exhaustive list, and while a single MP3 file could embed all of the above images, in practice only one image is ever usually embedded.
