I'm having some real frustration with the Media Library, as a WP beginner. What I'm expecting is that I can upload an image, and then reuse that image where I want within the site, using a standard identifier of some sort. Seems simple and intuitive, but apparently that's not how things work. I've been searching for answers, but a lot of the stuff I'm coming across... I don't even understand the wording of the search results and page titles....
What I'm experiencing (3.5.1, btw) is that images are uploaded and stored at a URL that has the date of upload encoded in it, so that even if I try to upload a new image with the same name, rather than replacing the old one, it is simply added, because it has a unique upload date.
I'm using a plugin that asks me to enter a URL for images that it is displaying. Now see how this works out: I have already added image X with a given date, and copy-pasted its URL into the plugin's fields for lots and lots of pages. Now if I want to change the image, there's no way to replace the image at a given URL and have everything just work! I need to go back and change all the many, many references to the unique date-coded URL, which seems crazy! I also don't understand the idea of "attaching" an image to a post/page. Why can it only be attached to ONE post/page?
I'm sure I'm probably missing something, but this is definitely the most frustrating aspect of WP for me. I guess if I were to boil this down to a simple question (because I don't want to hear someone tell me I've done it all wrong and have to redo the site from the beginning!), it would be:
How can I upload an image and give it a custom, unique URL that I can embed into other places in the site, and such that I can replace that image whenever I want, etc.
I hope this makes some sense, and that someone can help. I'm normally a rational person and good explainer, but I feel out of my depth with this thing... because of not having learned yet how to "think WP" no doubt. Thanks in advance.
