Image Manager Not Displaying Thumbnails or Images in admin

In the admin>Catalog>Products Or anywhere you add an image with the image manager or anywhere an image is to be displayed. there is the blank noimage icon or logo that shows there. But if i manually switch the url in the address bar to http://mysite.com/admin/ instead of the https... then the images show up.

How can i fix this?

My two config.php files are correct for the https settings.

This happened after migrating from another host and copying from a different site. so this does have a new url. But as i said ive gone through and made the correct changes in the config.php files.
In admin > System > Settings I have enabled to use ssl

everything looks correct. but the only way i have gotten the images to show is by manually switching the url of the admin page that im currently with in to http:// to show the images. Please help.

The problem was definitely when i reentred the new website info in the config.phhp file in the ADMIN folder

define('HTTPS_CATALOG', 'https://mysite.parts.com/');

is what it was... I looked at it 100 times and missed the fact that i needed to remove the .com

final change:
define('HTTPS_CATALOG', 'https://mysite.parts/');


So lesson learned... don't skim over details. make sure everything is 100% correctly typed.
