Well, I did more research and I found three new articles, one of the authors better explain the way to use picupapp to retrieve photos from iPad, the other shows a way to resize and upload a photo and the last showed how to, locally, store photos with HTML5 LocalStorage API.
But with my limited programming skills I can not understand how to mix they, in a way I could do what I want:
- choose photos, from an iPad or from a PC.
- resize the images, to limit on iPad size 1024x768.
- upload the photos to imgurl (for backup).
- retrieve the photos in LocalStorage, to do not need to stay connected, to Internet, to use it.
If someone could help, I will apreciate.
