GSMarena.com try to show the exact pixels of the image (3264 x 2448 pixels).

Its not Firefox issue.

Your issue has nothing to do with Page Zoom being used for that domain.

It has a relationship to the Firefox image-resizing feature being overridden by use of JavaScript links being used by that website to open those images. javascript:ShowImgB - this script shows those images at their native resolution [as jay mentioned], and overrides the the image-resizing feature.

By way of comparison, view this image (which is displayed directly from their content delivery network {cdn} - not diaplayed thru the bog domain) and notice that the image is resizeable (as long as you haven't changed the browser.enable_click_image_resizing preference in Firefox hidden prefs)

Thanks for the reply, i understand gsmarena configured it so.

But again if have to see image, we have to zoom out and website becomes unviewable. Again have to zoom in and zoom out for every such picture we view.

Can firefox do something about this? like force re-sizable image Hope it would make firefox experience better.

Firefox should try to fix a fault with the webpage?

Have you tried loading those images with Internet Explorer? Or Opera?

For me, IE 8 shows "Internet Explorer cannot display the webpage" - the image loads very large, like with Firefox 21, but the rest of the PHP page doesn't completely load and that error / warning message appears.

Opera 12 shows the large image with this message.
"Could not connect to remote server
Check that the address is spelled correctly, or try searching for the site.

Sorry - IMHO, Firefox is loading that image (PHP page) as instructed, the fault doesn't appear to me to be a fault with Firefox.

Why not wait a few hours for some more opinions about this issue. There are a couple of other support helper's on this forum who have vastly more experience with this "web stuff" than I have.

One "dirty" fix for that which I can share is to use a bookmarklet to make the image smaller on the screen, once the "page" is fully loaded. Simply click the bookmarklet to "halve" the image.
https://www.squarefree.com/bookmarklets/pagedata.html
zoom images out = which will "halve" the image

That will help you get around changing the zoom factor for the whole domain every time you view an image on that website.

And if that "half-size" isn't small enough you can edit the "Location" line of that bookmarklet to a "decimal fraction" that is usable for your display.

This is the full javascript code for that bookmarklet.

javascript:(function(){%20function%20zoomImage(image,%20amt)%20{%20if(image.initialHeight%20==%20null)%20{%20/*%20avoid%20accumulating%20integer-rounding%20error%20*/%20image.initialHeight=image.height;%20image.initialWidth=image.width;%20image.scalingFactor=1;%20}%20image.scalingFactor*=amt;%20image.width=image.scalingFactor*image.initialWidth;%20image.height=image.scalingFactor*image.initialHeight;%20}%20var%20i,L=document.images.length;%20for%20(i=0;i<L;++i)%20zoomImage(document.images[i],.5);%20if%20(!L)%20alert("This%20page%20contains%20no%20images.");%20})();

This part of that string, near the end - .5 - is what halves that image.
%20zoomImage(document.images[i],.5);%20if%20(
Edit that .5 to .3 or .25 and see if that makes the image small enough to fit your screen.

Here's a little background on bookmarklets.

You can set the zoom behavior to be not site specific.
