my website loads large images only

Olivier

Hello,
.
I recently purchased a Files gallery license and it works very well, except for the speed of loading images. The reason is simple: high quality images (approx. 3000x4000 px) are loaded. The problem is that I don't know how to avoid this. Should I create small images? If so, where do have I to put them and with which structure? Do you have a link that would help me learn how to do it? I've already read the documentation without finding the answer.
.
Here is an example :

.
Another thing : I have paid the licence and installed the number into the _files/config/config.php file. But I can see a very little mention of "files gallery" under my galleries. Normal ?
.
Thanks,
Olivier

Ok, so one question at a time ...

First of all, about file size and dimensions of images on your website. This is something that all gallery website owners need to consider up front. If the purpose is to simply showcase the images to the visitor, then you should optimize the images for viewing from the web. I already wrote a post specifically about this:
https://www.photo.gallery/blog/image-size-quality-photo-gallery-websites/

Essentially, your images are too big (3-4000 px), and this is mostly a waste, because your visitors screens will shrink down the images anyway. By resizing your images down to for example 2000 px (still high quality) and saving with some compression (not generally visible), you can convert your 2-3 MB images down to 3-400 KB ... They will load much faster in browser of course!

Basically, you should either resize on your desktop BEFORE upload, or resize in the same process as uploading (when using the Files Gallery uploader, there is an option to "resize and compress"). There is no need to store multiple sizes. You simply store the large size that is optimal for viewing from the web. You can keep your originals locally, on your desktop ... Besides, it's better that you don't offer large original images directly to your visitors.

There is no "structure" or any change you need to make. You simply upload the optimized images instead of the originals, which are too large.

I checked the website you linked to, and I can see this is Embed gallery, which you don't have a license for. You have purchased a license for Files Gallery, which is used as the backend API (engine) for Embed. You don't actually need a Files Gallery license to use Embed, unless you are going to edit/manage/upload files from the Files Gallery interface. Effectively, if you want to use both Embed and Files Gallery without limitations, you will need a license for both of them (2 x $39).

Let me know if you have further questions.

Thank you very much for your replies.

1) I use big files because I want to show the work of the painter, who is very fine. I could compress a little bit more and downsample to 2500-3000 px, but I like the idea (and the artist also) to enlarge and look at the details. Before I was using Prodibi, who was excellent to do that, but it just closed a few days ago.

2) So I made a mistake. I understand that I don't need the Files Gallery but I need Embed Gallery, because I send the files with FTP : is it right ? Is it possible to change the license ? If not I will pay for both.

That said, it works great !

Ok. I think you could compress those images a little more, and get them below 1MB while still keep high resolution. You need to consider this: When a compressed image at 4000 px scales down to half size (or less) in browser to fit the users screen, any compression artifacts will also almost vanish to the naked eye. Of course, if the user zooms the image, compression may be slightly noticeable. So it's all a compromise ... Do you need to serve large low-compression images for visitors that want to zoom in? Or are you willing to sacrifice zoom quality to serve fast-loading images that still look great, for 95% (just a guesstimation) of your visitors that don't zoom?

Ultimately, you need to upload the images at the resolution you want them to load and display. Files Gallery isn't a CMS that will handle intermediate sizes and switch between medium-res and high-res specifically on zoom. Even if that's technically possible (painful to implement), it would then require 2x storage and a powerful server to automatically create the intermediate image sizes. Besides, what would the intermediate size be? Best is to simply target one high quality image that suits all screens and almost all purposes.

Olivier Before I was using Prodibi, who was excellent to do that, but it just closed a few days ago.

This is some website application that displayed different size images for different screen sizes, and loaded a larger version on zoom then? If so, is there any place I could see any example?

Olivier 2) So I made a mistake. I understand that I don't need the Files Gallery but I need Embed Gallery, because I send the files with FTP : is it right ? Is it possible to change the license ? If not I will pay for both.

I have create an Embed license for you. Did you receive the details? Use the link below to create a data-key:
https://embed.files.gallery/license/

data-embed-key="KEY_HERE"

Add the attribute to the Embed element in your html.

I will disable your Files Gallery license later. You will still need to have Files in place for Embed, but you won't be able to upload/edit files from the Files Gallery. You would need to maintain your Embed gallery by FTP etc.

Hello, we have the best customer service here!

Thanks for the license exchange.

For the rest, you are right and it is likely that only some of the visitors enjoy seeing the images 100%. I will look for the best compromise.

Prodibi really closed, so nothing is visible (between the announcement of the closure and the complete shutdown of the site, there were only 10 days! Incredible). I had to look for a solution very quickly. Prodibi hosted the images in high resolution and served them very quickly, then you could click on a detail which loaded instantly. It was a SaaS service. I have never found an equivalent. After what happened, I prefer a self-hosted solution like Files Gallery / Embed.

Thank you for everything !
