I can see all product images at the store level, but can NOT see any images in the admin area! Furthermore when I create a new product under admin, the "Browse Files..." and "Upload Files..." buttons are also missing.
I checked the var/log/system.log and see the following error each time i go to view the image tab:
2016-08-19T13:38:08+00:00 CRIT (2): Not valid template file:adminhtml/base/default/template/media/uploader.phtml
Could this be a file/folder permission issue?
Has anyone seen this issue?
Missing "Browse Files..." and "Upload Files..." buttons

This is what I see!
It's missing "Browse Files...", "Upload Files..." buttons and none of the images are showing up.

NOTE: New Discovery
Looking at the error log, I realized folder media/ and files media/editor.phtml and media/uploader.phtml do not exist! So I got them from the original Magento 1.9.1. and placed them under /app/design/adminhtml/default/default/template/.
The images showed up, But I am still missing the the "Browse Files..." and "Upload Files..." buttons.
Now I am trying to figure which files or folders are missing, to bring that functionality back.
Solved the disappearance of the buttons issue also.
While searching I found this link and found out that I am also missing another folder and it's content. skin/adminhtml/default/default/media/ which contained the 3 files flex.swf, uploader.swf and uploaderSingle.swf. Once I copied this folder the buttons appeared.
Also pursuant to the above mentioned article media folder should exist in the following folders:
skin/adminhtml/default/default
/app/design/adminhtml/default/default/template/system/config/system/storage
/js/tiny_mce/plugins/
design/adminhtml/default/default/template/
