Incorrect, I use a size 111x80, which is a perfect size for my iPhone 5, see this small thumbs album, you see at least 9 thumbnails simultaneously on an iPhone 5.
Most newer, responsive skins default to 160x160 or higher, where the image quality is less of a problem.
Much too large for an iPhone, see this large thumbs album, you see at most 3 thumbnails simultaneously on an iPhone 5.

It would be perfect if jAlbum could on request produce multiple slide and image sizes, so that I could use a small size for a small screen and a large size for a large screen.
I did request this in the past, but it has never been implemented!

So use HiDPI thumbnails. All the quality you need.

I do use HiDPI thumbnails in those 2 albums.
But your statement that the default thumb dimension should be 160x160 or larger is incorrect as long as jAlbum can not deliver more as one set of thumbnails.

So code your skin to do that. It's not difficult. That's how I generate large thumbnails for folders. And if you just want to display smaller slides or thumbnails on a small screen, use simple CSS media queries and show the slides or thumbnails with smaller dimensions - there's no need for a completely separate set of images.

OK, so like I said, there's no need for the Show thumbnails with high JPEG compression quality setting.

I agree with you on this point, I did even not know that such a dsetting did exist!

So maybe you should have looked at it before posting a lot of nonsense.

Well please show me the code how I could do that with a Justified-Gallery of thumbnails!

Yes there is, because if you scale down large images, the loading times are higher as needed.

I did react only because of your nonsense statement:

Apparently you haven't taken the time to look at the options that are already built into the JustifiedGallery script. But I'm not going to spend my time spoon-feeding you things that you're too lazy to look up yourself.

Rapidly becoming a non-issue. One of my houseguests this past weekend doesn't even bother with WiFi on his laptop any more. He just uses the cellphone network. The speed is virtually the same.

Your tiny thumbnails look like crap on a normal-sized monitor. You shouldn't be using them. You should be using larger thumbnails, and showing them at a smaller size if you want to make use of the limited space on a phone.

Enough. Stop now, or I'm going to shut you down.

Hi. I've made another beta update, this time reworked jAlbum's review mode. It now allows you to both zoom into images and to compare two images side by side. Try double clicking to quickly zoom in/out max.
Comparing images looks quite interesting. But it's only possible to compare a picture with the direct predecessor and direct successor. Comparing picture 9 with picture 1 or picture 20 (for example) should also be possible to make this function more flexible. Just my thought.

I think it's a good thought. Currently I spent some work on synchronizing the navigation, but it's more intuitive and flexible to keep these two panels as two separate views that are independent of each other. Furthermore, if the user selects two objects in Explore view and fires up review mode (Space is shortcut) then I think those two selected imges should be shown at the same time.

The new preview has a minor oddity when viewing two images. If you have the left panel active and navigate to the last image, then both panels show the same image. If you have the right panel active and navigate to the last image and then back to the first image the same image is not shown in both panels, in either event.

Bug with new preview when the current explore view has a template page like About or Contact (with the rest being in subfolders).
