Answer 1

You can upload images using File.SaveBinaryDirect Method in sharepoint.

Go through MSDN, Also work in SharePoint Online.

Example

using (var clientContext = new ClientContext(url))
{
 using (var fs = new FileStream(fileName, FileMode.Open))
 {
     var fi = new FileInfo(fileName);
     var list = clientContext.Web.Lists.GetByTitle(listTitle);
     clientContext.Load(list.RootFolder);
     clientContext.ExecuteQuery();
     var fileUrl = String.Format("{0}/{1}", list.RootFolder.ServerRelativeUrl, fi.Name);

     Microsoft.SharePoint.Client.File.SaveBinaryDirect(clientContext, fileUrl, fs, true);
 }
}
