XnView Software

XnView MP is making thumbnails, but I would like to preload next image as I iterate through folder - so on moving to the next image it is displayed more or less instantly. Now it displays blurry and slightly distorted thumbnail that jumps a bit as full file is loaded.

Is it possible to do this?

Yes.

In 'Tools | Settings | View | Misc.' you should have checked the 'Read one image ahead'.

However, remember that if you move to the next image fast enough the storage layer (HDD/SSD + mobo/controller + a dozen of other processes which read/write from the HDD if you are on the OS disk) will NOT be able to keep the pace. AFAIK, XnView MP is the fastest browser around so I don't think that you can find a better solution for this.

It is enabled by default. Anyway, there is this worse quality phase also on slow moving through images.

I will try to check whatever it is possible to achieve better caching (by writing a test program), but probably the proper solution is "buy SSD".

Yep. Most probably you need a SSD since you don't work with RAW files (which have an embedded thumb big enough in dimensions to be used for preview and small enough to be loaded quickly).

Also, you can use another secondary HDD to put the files on it. It will help significantly.

...but what strikes me is that you want to browse very fast the images in sequence. Why? Do you want to "find/chose" a certain photo?

For this it would work better (IMHO) if you have bigger thumbs (let's say 3 columns only) and look there.

I filter giant collections of images (I never make photos, but I recently obtained photo collections from family members and friends).

Unfortunately most of them never tried to delete blurry, failed, ugly and duplicated photos.

Frequently there are many duplicates of the same image, and thumbnail are almost always not enough to decide which one is worse.

Aha!

1. If you have EXACT duplicates you can use Tools | Search Similar Files... or another program (Google for it) called AntiTwin - this isn't a image manager but a very neat and simple to use duplicate file finder.

2. If you have CLOSE duplicates (IOW you want to make comparisons and to choose which one to delete) you have Tools | Compare... (Shift+C) which has a more powerful tooling in order to detect which is better. Choose up to 4 images and press Shift+C to see.

You have there sync zoom (mouse wheel) & pan (Left mouse button + drag), also you have single zoom (Ctrl+Mouse wheel) and single pan (Right mouse button + drag). You have also right click menu and also you can show/hide the strip of thumbs on bottom or on the left side on the screen in order to choose new images to compare.

Of course you can do enough actions there, including Delete.

Look around on the Compare tab and I think that you'll get used quite easily with it.


...But if you want to just quick scroll between the photos then you just need a better sustained data rate from the storage (IOW, a faster drive and/or a less busy one).

You can adjust the minimum size in .ini with prevSize
