### Extend to other markup languages ###
Simply add a custom paste function that accepts the relative path to the image as an argument, and set `g:PasteImageFunction` to the name of your function. E.g.
```
function! g:LatexPasteImage(relpath)
execute "normal! i\\includegraphics{" . a:relpath . "}\r\\caption{I"
let ipos = getcurpos()
execute "normal! a" . "mage}"
call setpos('.', ipos)
execute "normal! ve\<C-g>"
endfunction
```
Then in your .vimrc:
```
autocmd FileType markdown let g:PasteImageFunction = 'g:MarkdownPasteImage'
autocmd FileType tex let g:PasteImageFunction = 'g:LatexPasteImage'
```
The former sets the (default) markdown paste function for markdown files, while the latter sets the new latex paste function to be used in latex/tex files. The above LatesPasteImage has already been added to the plugin, see `plugin/mdip.vim`. Existing paste functions:

| Filetype | Function name | Content |
|----------|---------------|---------|
| Markdown | MarkdownPasteImate | `![Image](path)` |
| Latex | LatexPasteImate | `\includegraphics{path} \caption{Image}` |
| N/A | EmptyPasteImate | `path` |

PRs welcome

### For linux user
This plugin gets clipboard content by running the `xclip` command.
