Feature request: Add a button to preload the large images

[wolph]

Instead of having the checkbox to always enable/disable preloading, it would be great to just press a button to preload all images on a page.

Also, after preloading it would be very useful to have a button to open the gallery :)

Always preloading is currently done like this in hoverzoom.js

{
clearTimeout(preloadTimeout);
preloadTimeout = setTimeout(hz.preloadImages, 800);
}

So all that´s necessary is doing that on a keypress. The keys itself are configured in options.js. An additional Action Key would have to be declared

actionKeys = [
{...},...,{...},
    {
            id:'preloadKey',
            title:'Preload all images',
            description:'Preloads all images on the page on keypress'
     }  ]

and loaded, i am however not sure how exactly that happens. My guess is that it could work by adding it like this:

function loadKeys(sel) {
$('<option value="47">preloadKey</option>').appendTo(sel);

I may or may not test if that would do the trick.

On original hoverzoom, when you click on the hoverzoom icon in the url bar, it brings out a popup containing, amongs other options, a link to preload all images on the current page:

@extesy Is the popup disabled here?

@AltarBeastiful It shouldn't be disabled. What happens when you try to click on HoverZoom+ icon?

Well now it's fine. I went to the background page, saw some error. Then the popup shows up. That's the popup while automatic preloading is going on. So compared to original hoverzoom, the popup misses :

• Disable for the site checkbox,
• Preload zoomed images link.

Could we add those easily you think?
