I converted my image to 100x100 (the largest size appliable to the profile pictures), sent it to myself, and copied the URL. You could also save the 100x100 image to your files, and put it into a URL converter. I used imgbb.com, the site lets you upload the image, then gives you a URL that should be compatible to the website, unless the image is too large.

@daedranthusiast That's bullshit, the file size is way too damn small. I know this site was made in like 2013 or something but come on

I know it's a bit much for an icon, but it's the only way I could find. I'll come back here if I find an alternative.

Your photos are great and I'm sorry you had difficulties with the thumbnail. I love images and it doesn't matter to me what size they are, but unfortunately when I need to zoom in or out I don't know how to do it. Also recently I have fallen in love with vectors, especially femida . She represents the symbol of abstract justice. It's so great when there is a certain history and meaning, it fascinates me.
