Sorry but I could not re-size the above photo of Gene eating his fillet-o-fish sandwich. I remember when he bopped a guy about ten years ago, who was messing around with him while he was out for a drive

GREAT. How wide-ranging do you wanna make this thread anyways!? ;)
Quick image resizing lesson.
You can use the modifier width="xxx" to make an image xxx pixels wide. Aspect ratio of the image will remain the same.
Or you can use the modifier height="xxx" to make the image xxx pixels high. Aspect ratio of the image will remain the same.
Or you can use the modifier width="xx%" to make the image xx% of the width of the browser window. This is handy as it will automatically resize the image to whatever size the browser window happens to be.
So, typing <img src="https://nypost.com/wp-content/uploads/sites/2/2023/03/NYPICHPDPICT000007831829-1-edited.jpg" width="200"> gives us:

And typing <img src="https://nypost.com/wp-content/uploads/sites/2/2023/03/NYPICHPDPICT000007831829-1-edited.jpg" width="75%"> gives us:

The first image will remain 200 pixels wide no matter the size of the browser window. The second image will automatically resize to 75% of the width of the browser window as you resize the browser.
There ends today's HTML lesson. (Mostly because I've now exhausted my HTML knowledge...)
the option that you add to your image is
width=500
to make it pretty fair sized for FR. The one you posted was
width=2500
approximately.
From Section 4B.2 of the Free Republic 2021 Sandbox:
img src="Image Link" width="x%"/
Using < before and > after of course.
30 to 40% usually works well
