First you have to upload an image from the three vertical dots and click 'Upload File' (nothing upwards of 7+ for the age requirements, please)
Then you use this script:
<div class="card"> <img src="example here.extension here" alt="example here.extension here">
This is a very basic script. The alt function is when the main file can't load. A
lthough if you wanted to adjust the dimensions of the file (height and width), you would need to do this:
<div class="card"> <img src="example here.extension here" alt="example here.extension here" style="width:__%""height=__%"> </div>
That adjusts the height and width of the file.
NOTE: Do not forget the <div class="card"> otherwise it will not work.
