Anybody know anything about the fact that when I upload pics, they come out motherf-ing HUGE as hell!?

Like I mean I gotta take 'em into Photoshop and size 'em down by like 50-75% just to make 'em fit on the page. There any setting or something for this site that'll fix it?

Cuz I gotta be honest, if I gotta resize my pics for this, and FA, and RedBubble?! I won't be uploading here much. I'm already uploading on four places with every finished piece... streamline my shit, guys. I don't have the time to be personalizing my shit for every site I'm using. Especially when RB means it's gotta be OMG HUGE AF! I'm serious. I've NEVER had that much canvas space before. I SQUEAK by with high res, but c'mon! Y'all have to know what it's like trying to get it BACK down to something I can upload anywhere else!

UGH! --flops-- Anybody have answers?
