Messed up persona theme

I tried my hand at making a persona, https://addons.mozilla.org/en-US/firefox/addon/yet-another-grey-theme/

I do know I uploaded the header at 3000x200 as well as the footer at 3000x100. And the images I uploaded were convex, not flat. However when I uploaded it & it was approved, I installed it in Firefox 43.0.3 and it’s completely flat. Weird thing is, they look correct when you look at the theme’s page. But in use, it’s the right color, but wrong shape. Now my screen is 1366x768, but one would think you would see some 3-D effect.

What did I do wrong?

Note that only a small section of the image will be visible when you install it, so a subtle gradient may look fairly flat. That might be what is happening in your case.

Ah, I see. Thanks for the info. :wink:
