Validation before upload

Before an image is uploaded, the plug-in validates it's mime-type and image file size. Depending on the validation result, an image upload is initialized or it's stacked as upload and update error.

upload and update workflow

The workflow concept is described here, and it can be configured depending on your requirements.

imageAllowedTypes​

The option imageAllowedTypes restrict what images mime types are allowed to be uploaded using RESTful service.

Initialization JavaScript Code
function( pOptions ){
  pOptions.imageAllowedTypes = ["jpeg","jpg"];
  return pOptions;
}

imageMaxSize​

The option imageMaxSize restricts maximum image file size to be uploaded using RESTful service.

Initialization JavaScript Code
function( pOptions ){
  pOptions.imageMaxSize = 1024*30; // 1024*30 = 30 Kilo Bytes
  return pOptions;
}
