Responsive layout is of course good for mobile platforms, but it´s not good on big screens when the maximum image size is exceeded. Is there a way to put a maximum upper limit to which image will be exposed? I have found maximum size setting for page, but I guess that something else.

Thank you for replying! Even when setting the album in this way the images are scaled up. (I am using HiDPI images, if it may affect this). The test-album is here: www.cherrug.se/Test2.

Thank for your explanation! This is however not a solution because I am losing to much in image quality using e.g. Retina displays. Have to stick to Turtle then.

No, way too complicated. I think the answer is simpler than that. There really is no such thing as a "HiDPI image." It's just an image that's twice the size. So how does that work? Simple. jAlbum just lies to the HTML about how large it is.

A simple HTML skin doesn't ask the JPG how large it is. It asks jAlbum, and then does something like this:

<img src="${imagePath}" height="${imageHeight}" width="${imageWidth}">

So, the lie works, and the browser shows the image in a space that's actually half the size of the image. For a retina display, that's great, and for a normal display it's undetectable, other than having to do some quick browser resizing.

In a scripted skin like Matrix or Tiger, that's a problem, since the script normally isn't asking jAlbum what the image dimensions are. The script is just looking at the JPG itself, and not enlarging it beyond its actual dimensions. So the lie doesn't work.

I'm not sure how, but Turtle is currently doing this correctly. If you tell it to "shrink only," and give it a HiDPI image that's actually 2000x1600, it never shows it larger than 1000x800. Apparently, Turtle is paying attention to the phony imageWidth and imageHeight numbers that jAlbum is cranking out. So it does what's intended - it shows the image in half the space of its actual dimensions. Good for retina, with its higher pixel density, no problem for regular displays.

So what's the answer? Somewhere in your script in Tiger, if the choice is never to enlarge the image beyond its real dimensions, the script needs to say, "don't make this bigger than imageWidth x imageHeight, regardless of the JPG's actual dimensions."

Yeah, I find stuff in my own code that I wrote only a few months ago, and don't remember at all. But then again, I'm an old man, and I'm confused.

Didn't you mean 'Link to scaled down images only'? Originally you wanted to link to originals but originals are always shown as full size.

In my case the originals are already in the desired, scaled size, as I generate that size from the raw converter. So I do not need to link to scaled down images. Up to now as I have not been able to achieve HiDPI in Tiger, I have generated images 1080x1080 that are my "originals" in jAlbum that are shown in the Lightbox of Tiger. Now if I can constrain the main image in the Lightbox of Tiger to 1080x1080, I will generate the "originals" to 2160x2160.

Ok, thank you jGromit for sorting this out and why the need to tell jAlbum to link to scaled-down images. The result that I am after is as you describe it, I will give it a try for testing with another skin.
