When editing HTML documents containing images, you need to find out both the width and the length of each image and then feed every <img> tag. Just use perl by adding what follows into your vimrc file. When you hit F4, vim will get the image name and path mentioned in the "src" field of the <img> tag and will use perl to do this job for you.
Copy and insert image size into html code by pressing a key
First step is to make sure you have Perl installed and the Perl module Image::Size. Then all you need is to add this to your vimrc.
" Get image size with F4 with perl Image::Size module. function! PerlImageSize() g/src normal $ normal N normal 2w perl << EOF use Image::Size; $jo = VIM::Eval("expand('<cfile>')"); $size = Image::Size::html_imgsize("$jo"); VIM::Eval("setreg('a', '$size')"); EOF normal $ normal "ap endfunction nnoremap <F4> :call PerlImageSize()<CR>
- Another mysterious tip. What image? What does it do? What is the $ N 2w stuff?
- An example is needed because clearly the author has something in mind, and there is no need to perplex each reader of the tip.
- What is the g/src?
- The consecutive lines using normal can be combined to one.
- Check that the standard indenting I applied to the function does not break the Perl code.

- I think it's any image included in html with an <img> tag. But the tip obviously assumes some things about what has already been entered into the text and the formatting. These assumptions should be eliminated or documented. --Fritzophrenic 20:34, May 31, 2011 (UTC)
