can't embed if it was for my life
That's because you try to embed the gallery page, not the image.
Right click on the image in the gallery page and select "open picture in new tab" (this may not be the exact wording as my IE edge browser uses Dutch, but I guess all browsers have this option in some form)
Now, copy the url from that new tab. It should be an image format, like .png or .jpg
This url can be embedded with the IMG tag.
