I'm trying to upload a new, customized theme for my Firefox browser & I don't know how to resize my image(s) to meet the "3000 x 200 pixel" requirement for my images.

Best is to ask advice at the Add-ons forum. This forum is about issues with Firefox and that doesn't include developing lightweight theme (Persona).
