I have a WAMP installation of my live site running on Windows 7 using the WordPress WAMP stack from Bitnami. When I try to upload an image file to the WAMP installation, it does not work. I can see that the image is processed and placed in the uploads folder, but it does not become active. The only way I can get it to work is by explicitly filling in the pathname for the image in the theme options page, as shown below:
I have tried it using Firefox and Chrome, and the outcome is identical.
While I understand that I don't need to "upload" images since I am on the same machine and can simply do a copy to the uploads folder, using the "Upload Image" interface is necessary to generate versions of the image at various resolutions.
How can I get the WAMP stack to behave identical to a live site, and how can I go about debugging such a problem?
I am running WP 4.4.2 for both the WAMP install and the live site.
