Some discussions in Stackoverflow say that storing the picture in DB is a bad idea (a because overtime, the number of images get large & may lead to app crash). So, either

a. the image can be stored in the iPhone itself & only its location can be stored in the DB
Potential Issue: The image might get removed (outside of the app) & the app might not be able to load them the next time

b. the image can be shrunk to a small size (say, 100*100 pixels) and stored in the DB
Potential Issue: will size be an issue if the image is shrunk to just 100x100pixels?

c. Doing both (a) & (b). So, small versions of the images will be stored in the DB and then, retrieved & displayed in the App, whereas, if the user chooses to see the original version of the image (whose probability is low), then that’ll be fetched from the local directory & shown.

Your suggestions please? In my opinion, (c) seems a good option to go in for, in case (a) has the potential issue mentioned.

    It really depends on where the images are coming from. Are they being downloaded from the Internet (or imported from the user’s library / camera) after the user installs the app, or are they bundled with the app from the App Store?

    If the images are being downloaded / imported, the best solution is to store images in the filesystem following the recommendations in http://developer.apple.com/library/ios/#qa/qa1719/_index.html

    Basically, if the images cannot be replaced or recreated, store them in the <Application_Home>/Documents directory and do not set the Do Not Backup attribute. These items will be backed up to iCloud, and this data does persist for at least some amount of time even if the app is deleted from the device. (Remember that your users do not have unlimited iCloud space. Be responsible.)

    -However-

    If the images are bundled with the app, the best solution is to import them directly into your Xcode project and reference them from there. This way you know they are always available even if the user deletes and reinstalls the app.

    I would definitely stay away from storing image data in the databased whenever possible. There are simply better, more efficient ways in most any scenario.
