This is just a general question as to how the image_picker plugin works. When I select an image from the device gallery, the path is something like this: "tmp/image_picker.jpg". This is obviously not the original path of the image on the device. Does image_picker make a copy of the image? If so, where is it stored? Is it stored in the app data?
Maybe someone could point me to a white paper that explains all of this.
When I take a picture using the camera and image_picker the filename has the similar tmp path. The image can be reloaded by my app, but the image is not available in the device gallery. I understand that there are plugins to save the image to the gallery, but I would like to know how to delete the extra images from the tmp folder.
You can check this screenshot & link.
Note: Images and videos picked using the camera are saved to your application's local cache, and should therefore be expected to only be
around temporarily. If you require your picked image to be stored
permanently, it is your responsibility to move it to a more permanent
location.
Also same for gallery images because every time file_path will different because the library will store image in cache / temporary storage.

I have created custom Audio Component in Asset share commons in AEM, everything is working fine except I am not able to get the thumbnail in audio file (.mp3 and. wav).I have done some R&D then I found that Audio files does not have any rendition except original one. So my requirement is that is there anyway that we can add thumbnail in audio file.
PFB Screenshot of .mp3 node in crx.
See in above picture there is no rendition except original one that's why it is coming as without thumbnail, When I copy any image and paste it here (manually) then thumbnail is appear in audio files.
But I don't want to do it manually this thing. Can you please suggest some way how can I solve this issue? It will be very helpful for me.

Look for the DAM Update Asset workflow. There is a step, Process Thumbnails in which you can add the MIME types for which you would like to generate renditions (or skip them as well).
e.g. http://localhost:4502/libs/cq/workflow/admin/console/content/models.html
In my application users can add up to 8 images taken by the camera and upload them to the server one-by-one.
My problem is that even when taking the first picture i get an memory warning, which of course forces the app to release any view not visible.
What is the best practice approach to handling pictures?
How do I hold them until they're uploaded, without running out of memory?
My objective is to avoid any memory warnings.
Thanks in advance.

After clicking images store images into Document directory. It is most safe option to store
images and then use it. Find some tutorial and after click image send image to document
directory and then fetch from directory and use it. Hope it helps you.
Proceed Following steps.
I am faced like this problem, now it's working for me use following steps.
Select image and and display to UIImageView. then Upload to server.
Release UIImageView.
Again take picture and upload to server.
For example, I can convert the second image into NSData and then place it inside metadata inside the first image and then when I open the first image and read the metadata I can get the NSData and turn it into an UIImage.
How would I go about doing this? All the metadata tags I see are not large enough to support another picture. I know picture in picture is quite common on desktop apps so I'm interested in getting it to work on the iPhone.
Is metadata the correct way to do this or is there another way?
If I allows users to select photos and need to store those selections (in a database), can I store a link to the selected photo or do I need to grab the image and store it in the app's Documents folder? The latter doesn't seem practical since it will cause the image to neednessly take up double the amount of space.
I'm familiar with UIImagePickerControllerDelegate but not sure how to obtain a reliable reference to an image that sustains across application restarts. There is probably the concern that the link can break if the user deletes that image from their photo library. Is there a way to check that?
There is no way to get a file url to an image stored in the Photo Library.
If you really do need to keep a reference to the file for programatic reasons, then choosing the image from UIImagePickerController and saving a copy to the Documents folder is probably your only option.
It would help if we could understand why you require a file reference to the image. As far as the iPhone is concerned, the image is safe and sound in the photo library, if user needs it, it can be picked from the image picker, like normal.
However, if you're trying to use it for a customisable background or something, then I think saving a copy is your only option.
It looks like I cant create an album for my picture producing app in the photo library... so what I was going to do is save the images to the documents folder for my app, which I think should be easy enough. The issue though is that the image picker seems to only allow you to pick saved images or photo library as the source, and I would like users to be able to view all images created by my app. Is there a way to make the picker work or will I have to roll my own?
the image picker that apple provides only gives you access to pictures saved in the camera roll. It also gives you the functionality to take a new picture if you are on an iphone. If you save pictures in your app's local storage directory, then you need to build your own mechanism for viewing these photos. You may want to take a look at Joe Hewitt's 320 project - it has a lot of good controls that you may find useful.
