How to store and extract images - react-native

We are having an exercise on making mobile apps. Currently, we want to render each product and have their images attached. Initially, we refer to how to save images to a folder and save their path in the DB. but the problem comes when I call the API in React which gets this binding into a variable and can't use require in the Component Image. So we are thinking about converting the image to base54 and storing it. Trouble is, this string is quite large. Can someone give me advice on solving this problem, or a link to a tutorial.

React native image annotations containing a link to a site

I am a complete beginner at react-native. I am trying to create an app where i can take multiple photos and add a tag/label with a link to a website to each of the photos. These links when tapped need to take the user to the specified website. I also want to be able to save all of the tags along with the images for later in the app. I have found some resources(components) regarding this but as a beginner, i do not know how to use any of them. I am listing these below. If anyone can help to use these or give me any direction as to how i can make this project, i would be really grateful.
resources i found:

Xamarin forms Carrousel and take a picture async

I have been trying to replace my carrousel images with t new photos from my phone camera or album, but for some binding reason, they don't display on the carousel.
I am using Xamarin Media Plugin.
any picture I select should display on the carousel. I have been trying everything in here. IMAGE URL works fine, stored images in the resources folder, works as well. but, for some reason display the images from the media is been a nightmare.
You can clone my sample project # GITHUB
I will appreciate Any help.
Looking at the GITHUB project, easy to understand why no relevant code here, it will require the whole sample project. It seems the carousel is not getting updated when uploading an image, binding?? I am still checking.

URL link for the project reports for the PNG

Is there a way using a REST API or some other means to get the end point the URL which holds PNG for the iteration break down, velocity chart, iteration cumulative flow diagram for each project so that we can share it across.
Something like below

How are you trying to share it? If you'd like to embed it in a wiki or sharepoint it's fairly easy to embed a custom app with that chart in it. The generated report images themselves are not actually linkable- they are generated as a client side image map...

Dynamic User Interface in iOS

Im struggling with a thought here. Let's say a user has his own CMS where he can fill the content for our app. One of his options is to create a view by uploading images and typing text. Well keep it very simple and imagine he only uploads a image (320 x 20) and some text. So an image on top and some textlines below.
What would be the best way to let my app know of this layout and download the contents? I was thinking of a downloadable XML file which defines the layout but don't really know how to implement this or if its even the best way.
Oh and the content and layout must be downloadable for offline use too.
Another option what I was thinking of is showing the layout in a webview but I can't figure out how to download the mobile website for offline use.
A push in the right direction would be appreciated!
We use a custom XML and it is working good. All texts inside 'label tags' are in XHTML
remember to:
be specific when defining the xml to save some effort
write a limiting XSD! So nothing 'surprising' creeps into the xml
remember not include everything in ONE xml file as that would get rather large rather quickly. Choose a scheme for portioning the XML

How to load an image with unique names from a private folder?

I am working on an app for iPad where I want to have lets say 100 jpg's in a folder.
They could be named like 01.jpg, 02.jpg etc.
In my app I like to browse those images and when clicking on one of them I need the name of the image to be able to send some data over the network (the data part works fine).
I tried to use UIImagePicker but I found out there are no name connected to the actual image.
Then I made another approach where I have a number of pages where I have buttons and here I load in the images which works fine as long the are a part of the recourse of the project...
But here comes the real problem.
The user of the app should be able to change those images over time without recompiling the app.
So I do look for a way to have a folder where the user can place/replace images with the names 01.jpg etc and the app to use those updated images.
Ideas are very welcome.

I am not sure that I understand what you mean, but You can save images in your application documents folder. You can find more details at:
http://developer.apple.com/library/ios/#documentation/iphone/conceptual/iphoneosprogrammingguide/StandardBehaviors/StandardBehaviors.html#//apple_ref/doc/uid/TP40007072-CH4-SW6
You can also use NSFileManager to copy files.
what I suggest to do is :
put default images on project resources.
At first start, copy files to documents folder.
always use images from documents folder.
