I often set up draft posts by emailing pictures to my blog to add text etc. later. If, like me, you sometimes email multiple images from an iOS device and wonder what happens to the resolution if you resize it to Small/Medium/Large. Happily, a post at Senseful Solutions on iPhone Email Image Sizes has the answers, some of which are summarised below:
|Size||Picture (JPG)||Screenshot (PNG)|
|Small||320 x 239||213 x 320|
|Medium||640 x 478||426 x 640|
|Large||1296 x 968|
|Actual||2592 x 1936||640 x 960|
iPad screenshots are 768 x 1024 PNG files.
