JS+ Image Editor is the add-on for popular WYSIWYG online editors (CKEditor and TinyMCE) which lets you modify images uploaded onto your website.
It helps you to prepare images for publishing on your website: resize and crop them, rotate and write text over them, apply different image filters and use other handy tools.
Image Editor v. 2 now supports many different server sides (because of use uploader from File Uploader) and became more secure as far all editing is done on your side, finally modern browsers give us such features.
