how plugin work with different size image in the same page

Hello there,

Let me try to answer your questions:

1. None of the points you mention about Gtmetrix can be fixed by our plugin, unfortunately. But in this area, we believe Gtmetrix is wrong, because it is impossible to have responsive images with specific sizes. You will gain much more speed by serving smaller images than doing this. But this is another discussion and it is more of a a grid and CSS-related issue.

2. Our plugin works automatically. You tell it what image size you wish to have in the settings page and it makes sure that it will serve each device the best possible image for its dimensions. This way it serves a lot less kilobytes and pages load faster in mobile devices.

3. I am not sure I understood correctly your question about the slider images, but I believe that this is an implementation specific problem. It is up to you to specify one or more images and their dimensions in your HTML. The plugin will make sure it serves these images scaled down for mobile devices.

Let me know if I can help further!

thanks for clarification, i’m not a guru so i need a confirm that the first gtmatrix point in a responsive world is anachronistic;)

if your plugin serve re-scaled image according the viewport i think that it is usefull also for the second gtmatrix point. isn’t it?

i have bad english sorry. i would like to present an example of page displayed on a large viewport. So the images on slider we’ll be the most bigger size we have specified but i wuold like to know what happen for the other images.

i’m set 1080,600,300 in your plugin. This is a good chooise for image slider but for the others? we have to specifiy different size for each “type” of image:
– 1080,8600,300 for image slider;
– 300, 200 50 for thumbnails;
– ….

Let me rephrase that bit about Gtmetrix being wrong. Actually, it is not wrong. Technically it is correct. But it is not viable! It is practically impossible for a developer to have a specific different image size for each and every breakpoint they use.

In addition, we believe that there is a lot more to benefit from if the size of an image drops from, for example, 300KB at the original desktop size down to 50KB for a mobile screen.

As far as the 2nd Gtmetrix point, yes you are right, if our plugin works in your setup then images will also be optimized.

Unfortunately, it would be too complex to develop a feature where different images could have different breakpoints in our plugin. All the images have to be treated uniformly and this is done with respect to the device dimensions.

Hope this helps, a little more!

Thank!

just last question. so how is it possible to use your plugin in the correct way if i have (for example) this groups of images:
– image of the slider;
– image into the text;
– image banner;

i have to limit your plugin to be applicable only for a group?

Well you simply have to treat all your images in the same way. You specify your breakpoints in the plugin settings page for all your images. You can even leave the default options, which are pretty OK.

But the plugin will still handle all of the images in the watched directories! This is something you cannot avoid, because it is the way the plugin is designed to work!

Does this cover your question? ??

“Adaptive images plugin transparently resizes your images, per device screen size, in order to reduce download times in mobile environments.”

So with resize so do you intend image more light but with same px resolution?

No-no, we intend to actually resize the images! For instance when a device with a width of 320 pixels asks for an image, we want to serve it an image no bigger than 320 pixels! Of course device sizes are very diverse and we would not want to have one different size for each and every device, so this is why we define certain breakpoints! And for these breakpoints, we cache the images.

Then your plugin is useful also for 3th gtmatrix point? in other word it can serve differente image size according to the viewport.

if we have an original image of 150x150px (ex. thumbnail?) displayed for the bigger viewport? how this images are managed?

No not point 3, actually! This point refers to the actual sizes of images. But our plugin changes the actual size in the background transparently.

Now if you have an images which is already too small, like 150x150px then our plugin does nothing. I simply lets the original image to be served to the user.
