How to insert images into posts without using Add Media dialog

I want to simplify the process of inserting images when editing posts. In wordpress default, you have to click “Add Media” to show a popup dialog, upload images, choose from gallery.. it is too complicated.

My desired process is:

1. Click “Add Image” to show a dialog

2. Click “Choose File” and pick an image from your computer

3. Click “Upload” and wait for the file to be uploaded. Then image is
   inserted into post automatically

As an example, my desired process is just like the insert image button in the wordpress.stackoverflow.com rich text editor, you can click to see it (Sorry but I am not allowed to post images here)

I know stackoverflow upload images to a third party provider, but I want to use my own wordpress installation.
Also, I don’t care the Media management section (wp-admin/upload.php), I probably will remove it from admin panel.

My question is:

How can I implement a simplified upload images process in WordPress? Any plugin available?

The WordPress default media management system is pretty good and far better than what you want. However, you can use the Advanced Custom Fields to add image upload boxes in your post editor page.

Once the image is uploaded, you can display it in the editor using a shortcode [acf field="{$field_name}"].

Check out ACF Documentation for all the details.

This plugin is very easy to use. However, your image may not be processed by WordPress and other image processing plugins that you may have or will have in the future.
