Actually, I just noticed that the forum is compressing the picture considerably (1080x1468 to 367x500, in my case), so the original full-sized image should be sent to you in another way. WeTransfer, for example. Though I think a regular email should work.
I'd post them here on the thread only if I wanted to show it to the community in advance, because I don't think the forum is going to let you get any nicely sized picture.
Furthermore, and now that I think about it... There's an optimal width size for tapas submissions, right? Wasn't it around 900? I think someone brought that up in another thread. I haven't published anything there yet so I'm not sure.
