Question

Answer 1

• You can reduce the memory footage of the image using JPEG image compression

  lowResolutionImage = [UIImage imageWithData:UIImageJPEGRepresentation(highResImage, quality)];
  

  where quality is between 0.0 and 1.0

• Don't send the image as raw binary over the internet turn the binary into base64 string

because some media are made for streaming text. You never know some protocols may interpret your binary data as control characters , or your binary data could be screwed up because the underlying protocol might think that you've entered a special character combination.

Here is the link on how to convert into base64

• As you are using IIS for hosting your application, then the default upload file size if 4MB. To increase it, please use this below section in your web.config

  <configuration>
      <system.web>
          <httpRuntime maxRequestLength="1048576" />
      </system.web>
  </configuration>
  

  For IIS7 and above, you also need to add the lines below:

  <system.webServer>
     <security>
        <requestFiltering>
         <requestLimits maxAllowedContentLength="1073741824" />
        </requestFiltering>
    </security>
  

Note: maxAllowedContentLength is measured in bytes while maxRequestLength is measured in kilobytes, which is why the values differ in this config example. (Both are equivalent to 1 GB.)
