The FASO software supports image uploads on iOS 6 and above (later), not on iOS 5 and lower (earlier). This is a limitation of the earlier iOS versions.
If your device is running iOS 5 or earlier, you'll need to use the FASO app.
If you are running iOS 6 or later, you can
(1) upload images using the regular FASO uploader (in your browser) from your FASO control panel
See this FAQ: How do I upload images of my artwork?
(2) use the app
The FASO app is an iPhone app, not an iPad app. You can run iphone apps on an iPad but it is less than ideal and not necessary.

NOTE: You are limited to uploading 1 image at a time when using the App.
