Why can't I upload a new file to my media library?

f you’re not able to upload a file that is under the maximum file size of 25MB you might have run out of total storage space for your book. Each book in Pressbooks has a limit:

• If you’re a free user, you have 5 MB of storage.
• If you’re an EBOOK Pro user, you have 25 MB.
• If you’re a PDF + EBOOK Pro user, you have 250 MB.

If you run into problems and think you may be out of storage, try these steps:

1. Check your Media Library and delete any images that you’re not using.
2. Check the size of the images you’ve kept and see if any could be made smaller (for more information on image resizing, see this blog post).
3. Consider upgrading to a Pro package.
