can't find photos library to upload

Something must have changed during an update. When I want to upload a photo to a website, I cannot find the path to locate my photo library anymore. It no longer shows up under pictures (just brings a few random photos but not my entire library) and searching the rest of the folders it is not there including under photos (is blank).

My photos library can be opened and is accessible on its own, but I am just not finding it when the window opens for upload (in the screenshot attached)....does this make sense? The library location says that it should be under Pictures, yet it is NOT!
