How I can resize my image

Answer 1

<img src=… width=… height=…>

Answer 2

You can resize a <img> element by using CSS properties "height" & "width".
Here is an example of inline CSS :
<img src="myimage.jpg" style="height:100px;width:200px;">
If you want to keep the aspect ratio of the image, I suggest you search "max-width","max-height","min-width","min-height" CSS properties.
