I am creating app to display image from web services on iPad
I use FGallery to create photo gallery on my app and I retrieve binary image form web services and convert it to UIImage.
How can I add images to FGallery?
I am hoping that someone out there might have a solution that can perform this task, or if anyone could point me in the right direction, I would really appreciate it!
FGallery is current written to load images from the application bundle or web server via URL. Because you cannot change the application bundle at run-time, you will need to change FGallery to read images from <Application_Home>/Documents/ folder. Once that is accomplished, you will then save your new UIImage to the application documents folder and update the NSArray *localImages in the RootViewController.

The idea is that i will create a file in the app and store some data in it.
I want for the end user to be able to download that file from the iOS device to his mac/pc.
Is this somehow possible? Where should i put the file for the user to be able to download it via itunes?
Here is good tutorial you can use:

It is important to know, that in iOS, when your user needs to create file, you do not need to care where to save it.
Another possibility for you might be to avoid saving data as file. For example, if your data is picture:

I've been trying to get my app's tile to display an image from the web, but couldn't get it to work. I then tried the Tiles and Badges app sample, where in scenario 3 you can send a tile notification that uses a web image. No matter which image url I paste in the text box, the tile refuses to get updated. So apparently, the sample isn't working either, or something is very wrong.
The images are all smaller than 1024x1024 and less than 200KB. Fun fact: if I download one of the images I unsuccesfully tried to feed the sample, add it to the project and then send a notification using it as a local image, the tile gets updated. So apparently the image isn't the problem.
Has anybody been able to get this working? I don't get what I'm doing wrong.
Do have internet permission ticket in app manifest? Maybe only your app dont have permission to download your image from web.
I'm developing a simple web app and I just want to allow the user to upload some pictures.
should I just store the picture url on my database table or should I upload the whole picture?
how can I validate the size of the picture being uploaded?
how can I upload the picture from my controller?
thank you all!
I would NOT store the image data in the database. I would create a Behavior that will upload the image to the image directory and store a reference to that image. The behavior can then handle size, mime type, etc. Then add a file upload form to the controller and when the data goes to the model to be saved, it will automatically upload the image and put it where it goes.
If you do not want to build your own, here is a very popular behavior that someone has built.

Or you could try this simple way of doing it (check the readme.md file) :

I'm developing an application and I'd like to list the images present in the "Documents" directory of my application (to load images using iTunes) and I'd like to list the images and photos taken by the Camera as well.
And I do know about UIImagePickerController, but I don't need that. I want to integrate the photos and the loaded application images in the same place. But I can't find any information about where can I find all the device camera photos.
Thanks in advance
You can access all the photos stored in the photo library using the Assets Library Framework. Check out the documentation here:
https://developer.apple.com/library/ios/#documentation/AssetsLibrary/Reference/AssetsLibraryFramework/_index.html
Specifically, you want to use ALAssetsLibrary's enumerateGroupsWithTypes:usingBlock:failureBlock: to enumerate the ALAssetsGroupSavedPhotos type, and enumerate the photos in that group with ALAssetGroup's enumerateAssetsUsingBlock:.

You are getting url of the image. You can create the documentdirectory and save the images in that directory. http://developer.apple.com/library/ios/navigation/index.html?section=Resource+Types&topic=Sample+C#section=Resource%20Types&topic=Sample%20Code from this url you can find Apple sample code regarding url connection
