FCKeditor controls in JSP-file type and size control __jsp

(i) Control of file types
This is just a demonstration of the type of picture control, other controls need to see webroot/fckeditor/editor/dialog/below the corresponding JS file
fckeditor.properties Writing Reference fckeditor-java-core-2.4.1.jar/net.fckeditor.handlers/net.fckeditor.handlers/ Default.properties file
Myconfig.js Writing Reference Webroot/fckeditor/fckconfig.js file

If you want to add a new type of picture such as. ABC, modify the following method:
Add attribute connector.resourceType.image.extensions.allowed = Bmp|gif|jpeg|jpg|png in fckeditor.properties |ABC
Add fckconfig.imageuploadallowedextensions = "in Myconfig.js. (jpg|gif|jpeg|png|bmp |ABC)$" ;

(ii) control of file size

Modify the judgment before uploading files in Connectorservlet.java
