Inline Images

Per the org-mode [[http://orgmode.org/manual/Images-and-tables.html#Images-and-tables][spec]], you can include inline images as links without
any descriptive link text, like this:

[[http://farm5.static.flickr.com/4049/4358074549_5efb8b4903.jpg]]

I currently do not support the caption/link syntax, but I can include
the inline image. I recognize the following image file types:

- .jpg
- .png
- .gif
- .jpeg
- .svg
- .svgz

Sample absolute link to .svg:

[[https://www.w3.org/Graphics/SVG/Test/20110816/svg/animate-dom-01-f.svg]]

Sample absolute link to .svgz:

[[https://www.w3.org/Graphics/SVG/Test/20110816/svg/conform-viewers-01-t.svgz]]

Sample relative link to .svg:

[[file:images/animate-dom-01-f.svg]]

Sample relative link to .svgz:

[[file:images/conform-viewers-01-t.svgz]]
