Heyo!!!!!
Thanks for your responses. So basically now they're telling me that when I saved the file I saved it as a Progressive JPEG format and that I should try saving it as a baseline instead....?
I've uploaded my file here and even though again in preview on my Mac it looks GREAT, here it looks gross lol.
Also I added what the thumbnail of my book cover looks like online.
I don't know if this would be the issue, but...when I originally created the file I picked Web as the type but then when I put in the pixel size (1600X2400) it changed the type to Devices and I can't get it to not do that. I'm not sure why it did that as I'm not super smart when it comes to this stuff but maybe that was it?
Otherwise I have no idea and I'm just assuming it's something to do with how I'm saving it or somethings happening when I'm uploading it.
Help me please lol
THANK YOU!
Adam
