SharePoint REST parameter syntax

http://htvspt13dev1:1020/_api/web/lists/getbytitle('Events')/fields/getByTitle('Title')

To construct URIs that correspond to static methods or properties, use the corresponding API name from the ECMAScript object model, starting with the namespace declaration and using dot notation. For example, SP.Utilities.Utility.getImageUrl(imageName) in the ECMAScript client object model would have the following REST equivalent:

http://server/site/_api/SP.Utilities.Utility.getImageUrl('imageName')

http://htvspt13dev1:1020/Roblog/Lists/Photos/_api/SP.Utilities.Utility.getImageUrl('CEOBlogImg.png')
