Hi Maioli,

This functionality has been removed in version 7.6.0 : https://our.umbraco.org/download/releases/760/

And this is the related issue in the issue tracker : http://issues.umbraco.org/issue/U4-9720

If you need the thumbnails on the front end of your website it's better to use image processor to generate them.

Thank Dave, my site has a page with 60-80 photos. Each photo 5 MB. the render takes 3 minutes to display. with the 3 seconds thumbnails. is there a way to create the thumbnail?

davide

Hi Davide,

can you show your code to render this and specify the size the thumbnails need ?

Dave

Hi Dave, thumbnails:

        <img src="/media/1220/img_4342_big-thumb.jpg" alt="IMG_4342.JPG" />
    </a>
</div>

        <img src="/media/1221/img_4343_big-thumb.jpg" alt="IMG_4343.JPG" />
    </a>
</div>

Macro : Gallery

    <a href="@item.umbracoFile" >
         <img src="@item.umbracoFile.ToString().Replace(".jpg", "_big-thumb.jpg")" alt="@item.Name" />
    </a>
</div>

Hi Davide,

You can do this

<img src="@Url.GetCropUrl(item, 100, 100)" alt="@item.Name" />

Where you replace it with the correct sizes of your thumbnail

Dave

Hi Davide,

Your last post only contains 2 screenshots ? Do you have a question ?

Dave

If I created the thumbnail, I can directly see the image using replace (3 sec)

If I have no image created I tried with the new method inserted in 7.6 (180 sec)

Davide

Hi dave,

for now I have made a program in vb.net to create new files ( XXXX_big-thumb.jpg)

I have to run it every time I add photos.

Is there a way to make physical files when I load them?

Davide

Why do you need to program ?

Doesn't the @Url.GetGropUrl method work for you ?

Hi Dave, how can I make them create files?

Image Crop create RunTime Image

What is wrong with a "runtime" image. It will be cropped once and then served from cache until the original image or the crop changes.

dave

What you mean with 3 sec VS 180 sec.

A little bit more context please

Dave

50 photo on the page.

5-6 Mb for photo

120 sec with image process

3 with thumbail

Hi Dave, please check time http://www.tinbota.com/test/

Hi Davide,

That page loads for me in 7 seconds with a empty browser cache. That seems fair seeing the amount of pictures that needs to be server. It has needs to download almost 8MB.

You will only have a performance hit the first time the thumbnails are generated.

And if my browser cache is filled this the page loads in under a second.

A good option would be to lazy load your images. So the browser only downloads them as they come in to view ..eg the user scrolls down.

Dave

I also see the images are shown 200px wide on your site, but you crop them to 260px

So change the crop to 200 will save you several kb in download as well.

Dave

is working on a reply...
