SSL insecure elements from theme? | Forum

Having some issues getting my HTTPS to come up without insecure elements on my site.

Checked it using WhyNoPadlock.com and got the following but not sure how to make the necessary change:

Total number of items: 139

Number of insecure items: 3

Insecure URL: http://ow2/ow_static/plugins/forum/js/indicator.gif
Insecure URL: https://www.mysite.com/...es/miniic_corner.png
Found in: https://www.mysite.com/...se.css?4f7c716e73aa1

Insecure URL: http://www.mysite.com/ow_userfiles/themes/theme_image_24.png
Found in: https://www.mysite.com/...bre4f9458491a4e2.css

Any ideas on how I can correct these issues?

Thanks!
