Is it some configuration rule for multiple upload image in CKEditor image2 plugin? My current configuration is:
editor.ckeditor({
forcePasteAsPlainText: true,
extraPlugins: 'embed,autoembed,image2',
image2_alignClasses: [ 'image-align-left', 'image-align-center','image-align-right' ],
image2_disableResizer: true,
filebrowserImageBrowseUrl: '/laravel-filemanager?type=Images',
filebrowserImageUploadUrl: '/laravel-filemanager/upload?type=Images&_token=' + editor.attr('data-token'),
filebrowserBrowseUrl: '/laravel-filemanager?type=Files',
filebrowserUploadUrl: '/laravel-filemanager/upload?type=Files&_token=' + editor.attr('data-token')
});
