ZK Ckeditor is just a wrapper of CKEditor 4, and CKEditor config doesn't provide options to limit upload file size.

The possible way is to limit it at the server-side. CkezUploadExtension that handles the upload of an image doesn't implement such a feature, you need to subclass it and override private FileItem parseFileItem(RequestContext request) and migrate those codes in AuUploader.parseRequest() that use ItemFactory. Because ItemFactory can have a size threshold.

final ItemFactory fty = new ItemFactory(desktop, request, key, sizeThreadHold, repository, dfiFactory);
final ServletFileUpload sfu = new ServletFileUpload(fty);

Then add your custom extension with DHtmlUpdateServlet.addAuExtension(wapp, "/ckezupload", new MyCkezUploadExtension());
