The next set of options you will want to tweak are those involving adding images and other media to your blog. Click the Miscellaneous tab under Options to get to these options, as shown in Figure 14-13.
If you want to be able to add images and other media to your blog posts, you need to enable file uploads. WordPress usually guesses the Destination directory setting correctly. This is the full path to the wp-content folder on your server.
The URI of this directory setting is the web-visible URI the server will expose this folder as. WordPress sometimes gets this wrong. The URI it guesses works, but not all the time, particularly in the administration pages, so you cannot see your images in preview mode. Change this to an absolute path on the server. For example, if your blog URI is http://example.com/ myblog, set it to /myblog/wp-content. You can use a folder completely outside the WordPress folder if you like. For example, you may have an existing / images folder you wish to use. Whichever folder you choose, it will need to be writable by the web server.
The next setting on this page allows you to specify a maximum file upload size. You may want to set this to some value appropriate to the files you will be uploading. If you are going to allow other people to post and upload files to your blog, you may want to set this to a lower value.
The Allowed file extensions setting is a space-separated list of file extensions that WordPress will allow to be uploaded. You might want to add mp3 if you are going to add MP3s to your posts, perhaps if you are podcasting.
The last setting in this section is the minimum user privilege level required before a registered user is able to upload files. If you have multiple authors on your blog, you might want to allow only certain authors to upload files. You would raise their user level to this value to allow them to do that (raising user levels is discussed in Chapter 15).
The Track Links' Update Times check box refers to the blogroll-style links that WordPress supports. If you check this box and include the file wp-admin/update-links.php in your theme file, WordPress will automatically track the last time the blogs in your links were updated.
Finally, the "Use legacy my-hacks.php file support" setting refers to an old pre-plug-in system that WordPress used to support. As you are installing a new blog, you won't need to turn on this setting.
