I've created a lighter fork of the SimpleImage tool for Editor.js! It addresses a couple of issues I had with the original. First, it now uses blob URLs instead of base64, which saves memory. Second, it adds the ability to select an image file directly, rather than only drag-and-drop. Check out the fork on GitHub!
This post discusses how to use window.name for cross-domain communication between windows/iframes, especially before the onload event. It explains a simple method using window.open to set the name and retrieve it in the opened window. It also addresses IE compatibility issues by base64 encoding/decoding the data and provides code snippets for both encoding and decoding, handling IE's character restrictions and lack of built-in base64 functions.
