oh i just pulled the url from the page source. it's https://scontent-ort2-2.cdninstagram...ninstagram.com and then i put it between 2 image tags [IMG]put URL here[/IMG]. so i didn't re-up it anywhere.
but for image hosting, i prefer Imgur. there's a free option and of course, a subscription service for more storage and photo/image tools, etc.
what else is in this clutch BTW?
