In the Documents pane, you can create an image in any folder accessible via Texpad by either using your device's camera or by importing from your Photo Library. Simply tap on the '+' button in a folder in one of Texpad's local or Dropbox storages.

Images may also be imported directly into your LaTeX projects via their outline. Please see the section on 'Working with Documents'.

Note: We're often asked why Texpad is not listed in 'Open in...' dialogue for images. Users clearly wish to save images directly into their Texpad storage to include in their LaTeX documents. Well, sadly Apple won't allow non-Apple apps to register for images.
