Is there a particular reason why, in the year of our lord 2020, header and logo files in themes like Thanks, Roy are limited to 300kb? This seems ridiculously small, limiting, and unnecessary, and leads to a lot of image resizing hassles. Just curious.
I think that making this feature configurable would make the development of themes more flexible. I develop and maintain a theme for several instances of Omeka that uses a custom hero image, and for each instance I have to change the source code of Omeka when I need to change that variable.
