Manage Upload Types enables an administrator to add additional, or modify existing, uploads allowed by WordPress.

I use this to support .svg and .svgz (compressed SVG).

• 2022-04-20 – Switched to SVG Support

• 2022-04-20 – 1.3 on WordPress 5.9.3, with PHP 8.1.4

  • Cannot visit the options page.
  • I’ll stop using this. Alternative: https://wordpress.org/plugins/file-upload-types/

• 2018-03-07 – (version not recorded) – on WordPress 4.9.4, with PHP 5.6.33

  • It’s still working fine.

Configuration ∞

At the bottom, add Extension svg and Mime Type image/svg+xml

If uploading gives you a security error, then edit the .svg and make the first line:

<?xml version="1.0" encoding="utf-8"?>

See WordPress svg support for additional help.

I also add two other extension types:

Extension	Mime Type
svgz	application/x-gzip
asc	text/plain

.svg usage with BlogText ∞

2019-06-16 – This seems to be working just fine now.

Unfortunately, BlogText won’t render SVG images, so I have to manually link to them. =/

method one – non-resized linking ∞

Spoiler

This will expand to fill the browser/website.

method two – resized by a table ∞

{|
| width="150" | [[image:Open-source-hardware-logo.svg]]
|}

method three – manual linking ∞

1. Add a regular link, as above
2. Preview the page
3. right-click and copy the image URL

4. Paste it

https://blog.spiralofhope.com/wp-content/uploads/Open-source-hardware-logo.svg
https://blog.spiralofhope.com/wp-content/uploads/Open-source-hardware-logo.svg

You can also treat it like a regular URL:

[[https://blog.spiralofhope.com/wp-content/uploads/Open-source-hardware-logo.svg |link name]]
link name

You can optionally remove the beginning part, if you want to future-proof changes to your domain name:

[[/wp-content/uploads/Open-source-hardware-logo.svg]]
/wp-content/uploads/Open-source-hardware-logo.svg

or

[[/wp-content/uploads/Open-source-hardware-logo.svg |link name]]
link name
