6,719,913 | I currently have an image gallery with 30 - 40 images. Upon page load the user can visually see the images loading for a pretty significant amount of time (less than pretty). The gallery is using jcarousel prev / next buttons to navigate to images as well as thumbnails. I am looking for ways to optimize the way the gal... | 2011/07/16 | [

] | We implemented this in our website do the following thing.
1. When you construct the carousel , don't construct all the images with src value with images
2. For the first four or five images have the images for src attributes
3. for the next all images store the image valvue in some custom value and give src as some o... | Yes, lazy-loading of images is very neat technique to improve performance. You should show some of them (depending of size). Then jCarousel has a way of loading dynamically the rest of images:
```
jQuery('#mycarousel').jcarousel({

});
```
You can define that callbac... |

] | Indeed, the overwrite confirmation cannot be turned off with `:w!`, and `:set autoread` doesn't help in this case, neither. What does work is instructing Vim to explicitly check for changes before the write:
```
:checktime | w
``` | I believe
```
set autoread
```
should do it. It tells Vim to automatically re-reads the file changed outside Vim. |

```
set autoread
nnoremap <C-u> :checktime<CR>

Now whenever you want vim to reload external changes, just click `CTRL-U` :) |
