Okay so I'm going to try my best to show and explain whats happening here. I've given this problem to everyone on I know, college students in graphic design, art majors, etc. no one knows whats going on here.

The images I provide below depict whats happening to my original images when uploaded and viewed on my site.

For reference all my pictures are PNG. I never save to any other format unless necessary.

So if anyone would tell me what the heck is happening and how to fix it that'd be great. And hey don't judge, please!

And yes I'm sorry if this isn't really the place for it, but i wasn't sure where else to go with it.
