Will be great to have ability to view huge images in several resolutions (like 25%, 50%). Only highest resolution available currently. For example this one: http://commons.wikimedia.org/wiki/Image:1937_original_railroads_in_Pittsburgh.jpg
I don't think this feature is needed. It isn't often one wants to see a 25% scaled image, and when you do, it's pretty easy. For example, see http://upload.wikimedia.org/wikipedia/commons/thumb/8/82/1937_origina l_railroads_in_Pittsburgh.jpg/1332px- 1937_original_railroads_in_Pittsburgh.jpg for the 25% version, and http://upload.wikimedia.org/wikipedia/commons/thumb/8/82/1937_origina l_railroads_in_Pittsburgh.jpg/2663px- 1937_original_railroads_in_Pittsburgh.jpg for the 50% version.

Sure, this feature is not very necessary. I know only one use on Commons, who created pages for 25% and 50% zoom view. See http://commons.wikimedia.org/wiki/Special:Contributions/SPUI From other side will be useful to have options to view files smaller then original 10 Mb file.
According to a developer, "in principle we can garbage collect unused images (and in the future probably will) if it becomes an issue". Thus those pages may be required to keep the thumbnails. It would be a nice feature to have it automatic, so people don't complain about the existence of these pages (not sure why - they're only linked from the image descriptions).

In commons preferences in Gadgest is gadget: Choose Resolution: gives an quick link to other resolutions, for easy re-use of pictures. But this doesn't work on all images... I think that this feature without gadget is better think.

I'd agree. Looks like feature cruft.
I think such a feature is becoming more of a need, especially as file sizes and resolutions grow very large. We will soon have a Featured Picture in English Wikipedia, e.g., that is 37 MB ( http://en.wikipedia.org/wiki/File:Great_Wave_off_Kanagawa2.jpg ). So unless someone wants to download all that (or knows how to work the thumbnail syntax) they are limited to the default display size and cannot view a moderately-sized larger version. A Flickr-like feature that makes it easy to access a range of image sizes, and/or an option to download a reasonably compressed version of a file, would be helpful for users with slow connections. I don't think feature cruft should be a big concern right now for image pages, which don't have very many useful bells or whistles for the less wiki-savvy users.
There's a gadget on commons for that http://commons.wikimedia.org/wiki/MediaWiki:Gadget-ChooseResolution.js

We could add an extra sentence to the line "Size of this preview". This would then become: Size of this preview: 800 × 460 pixels. Other resolutions: 1024 × 588 | 1280 × 735 | 2048×1177 That would also solve bug 6834. Now do we want to make the sizes customizable using the MediaWiki: namespace?
> Now do we want to make the sizes customizable using the MediaWiki: namespace? I think that should be configurable at LocalSettings level, not at MediaWiki:
Something that I discovered while implementing this is that wikis that do not use 404 handlers will render all linked thumbnails when the image page is requested. I think this is an unacceptable performance penalty.
Why? It could be done via thumb.php, even if the wiki otherwise doesn't use it.

I'm gonna ignore the wikis that do not have 404 handlers. On regular pages many images are rendered as well, as well as on some special pages, so a few on the ImagePage should not be a big problem. I have made 6 linking style mockups: http://www.mediawiki.org/wiki/User:Bryan/Bug_2581
Done in r83791.
