Map jpeg uploads grey/low contrast??

Hi, I feel like this has probably been brought up before but I really can't find it with google: I'm uploading jpegs to the map layer, and they pop up grey/low contrast. Here's an example:  Image #1 is the map that I uploaded, viewed on my desktop, so you can see the difference.  image #2, on the left is my map image, it's all grey, as you can see. Right next to it is a map bought from the Marketplace, as you can see it's fine with full colour/contrast.  Things I've tried: - Turning off dynamic lighting. That wasn't the problem anyway, since the desert image from Marketplace looks fine - Checking that it's on the correct layer - Messing with image tint - Messing with GM Darkness Opacity, GM info overlay etc.  - Viewing as a player. Still looks the same Would it be to do with my jpeg properties? I think Illustrator exported a CMYK jpeg, though I'm not an expert on that kind of thing. Or would it be something else? No wrong answers! Thanks a bunch in advance!! -Josh
Here's a slightly clearer demonstration:

Make sure you are using RGB mode in your photo editing software. CMYK mode is for largescale printing businesses/specialized physical printing.
Well darn, that fixed it! (My illustrator settings were on CMYK from a PDF that WAS for an industrial printer hehe) I'll leave this post up as a warning I guess: Don't upload CMYK images to roll20!!
(I am, it turns out, a big idiot)

Wow, I would not have expected that to be the solution at all. Roll20 internally converts all uploaded images to png format (or used to--haven't tested in a while), which does not support the cmyk color space. Maybe that is where the tint was coming in. Must experiment.
