Anyone if you can help. 

I can't find out where to upload my pics anymore in Magento 1.7.0.2.

I don't know much about it, only a tiny bit. 

I have no developer to help me. I used to be able to upload but now I can't find the button not sure where to go. Tried inserting a picture here of my screen but not able to.

Anyone know what it even looks like the button? I am in pages in the backend trying to edit it in the wysiwyg part. 

I clicked on icon of tree to upload picture but I can't I can only insert pics not what I want.
