How to get an image and control it's size using JavaScript? [SOLVED]
I'm making a code where I need to get an image drawn only once. I've got the url, but none of the suggestions in the StackOverflow about how to get it is working in the Sololearn console. It'll be very cool if someone helped🙂 //Please inform me if further details is required

If you want build an image, look at this example of a circle and a square drawn in JavaScript.
One case without Javascript. After the header data, comments and the title "Normal HTML here."
It starts with the <svg> tag, determines the circle properties with the <circle> whose attributes are cx (position on the evaluated axis), cy (position on the axis). ordinate), r (radius), and fill.
For drawing the rectangle, the <rect> tag with its attributes, x (position in advertised), y (position in the ordinate axis), width (width), height (height), stroke (contour line) and fill ( fill).
Then they wrap the <svg> tag and the html tags. Such <circle> and <rect> do not need to be enclosed with the same text. Just use />.

Functions and Parameters
In this other example (see https://www.line.com.com/javascript/javascript-changing-size-of-a-image), He throws the <script> tag between such <head> </head>, a function that enlarges the image (id name), concatenated name is width, = name, width +50 and the same for height; one for normal size (id name), concatenated name with width and assigns value, name with height and also assigns a value.
In such a <body> he launches the image and the oneclick event (aumented size) with the image and id "logo" function. Then the ondblclick event with the normal size function. Then determine the cursor model.
