Hi Edvard,
I've done it, but my NT mobile app, its essentially hand coded. Plus, I'm a bit behind the latest version of NT.
So maybe someone else knows whether it can be done with stock NT (Even if it can't the html required to access the camera is simple).
Meanwhile, if you are interested, take a look at:
https://freedom.litehouse.com.auaccount = 14
login = bs
password = TempPassword!
You can see how it works using say Chrome, iPhone, Android or iPad (just try it from each device).
To find the photo bit in the app:
1. select "Listings" on bottom menu, then Listings again on the popup.
2. click on any listing
3. click on second tab "Photos"
4. click on the icon of a camera (right hand side)
5. After you select or take a photo (iphone will ask if you want to take a photo or select one from the library)
6. The [Upload] icon will appear, click it to upload the photo. New photo will appear at the bottom of the list of photos.
(i've given you a mostly empty dataset, so there isn't much else in the app).
Regards
Bill
