+## images_dataimg_filter
+
+This option lets you specify a filter predicate function for disabling the logic that converts base64 images into blobs while within the editor. This is normally used for very advanced integrations where you handle all base64/blob images with custom logic.
+
+**Type:** `JavaScript Function`
+
+##### Example
+
+```js
+tinymce.init({
+  selector: "textarea",  // change this value according to your HTML
+  images_dataimg_filter: function(img) {
+    return img.hasAttribute("internal-blob");
+  }
+});
+```
