In the normal way you use
<img src="…" alt="…" />
but some time you have to embed the image into HTML tag.
The format to use is the following:
data:[<MIME-type>][;charset="<encoding>"][;base64],<data>
and in my case (I wanto to embed a png image) I will have:
data:image/png;base64,<data>
Here the steps (how to convert img to data);
1) Open image with notepad++
2) Select all with CTRL+A
3) User plug-ing “MIME Tools | Base64 Encode” to convert the image selected.
4) move new data as below
