At the moment there is no proper documentation about its features, however further reading this post, taking a look at the archive or the preferences of the extension may give you an idea what's about.
By the way, this project is still under development, it works pretty well, but use with caution.
When reporting a problem, mention the name and version of your browser, also try to include sufficient information about your issue ("doesn't work" type reports should be neglected).
When requesting support for a site, give concrete examples/links, not just the name of the site.
In Opera 15+, the extension must be manually enabled in the Extension manager (Ctrl+Shift+E) after install.
ViewerReplaces the browser's default image viewer to a more customizable version. For instance, it's possible to set the initial sizing mode or disable the resizing totally, it can detect if an image has higher resolution, adds possibility for rotation, options for changing background color or image border, zooming to a selected area or zooming with mouse wheel, and more...
Hover zoomEnlarges thumbnails and linked images (or even linked thumbnails) into a pop-up with just hovering the mouse over them.
As well as the Viewer, it's also fairly customizable with some extra features, such as full-zoom which allows you to view the image with original size in the same tab allowing for further zooming. It can load image albums as well.
ToolsThis section contains global features or features that have less options.
Shortcuts - they can be used both on Viewer and Hover zoom
Opening images - many ways for opening images from web pages (e.g., background images)
Send image to... - it sends the image address to an online service (e.g., reverse image search, image editor, gif frame extractor...)
New service can be added in preferences (one per line).
Format: "[+]Name|search engine's URL". In the service URL is placed the image address with the %url variable.
If you put a "+" sign before the name (e.g., "+TinEye"), then it means that the service will be used when the shortcut is used. Multiple entries can be enabled, then all of them will be opened.
SieveThis is a set of rules which are helping the extension to find the larger images.
GalleryThis is something like a bookmark for images. It stores only the image address with a thumbnail, and if possible, then one or two source link. The "Source", which is the address of the page where you've seen the image, and the "Target", which is the address of the link (if it wasn't the same as the zoomed image address).
When an image is opened or "hoverzoomed", then pressing the shortcut (G by default) will add it to the list without any questions. Shift + G will prompt for labels. Deleting images from the list: Ctrl + Right click on the thumbnail cell or Ctrl + Click to select some and the minus button from the button-list. Shift + Right click on a cell to edit the labels.
GrantsAt Grants you can tell on which sites can the extension work.
It's also possible to block just some Sieve rules.
Syntax: grant operator (optionally followed by rules separated with commas) colon address
Also there is possibility to add comment lines, simply by starting the line with a ; (semicolon).
When you double the grant operator (! or ~), then it means that you want use regular expression in the URL. "*" means everything.
Example for blocking on all sites:
!:*Blocking all sites except opera.com (actually it will allow any URL that contains the "opera.com" string, and yes, the order matters):
!:* ~:opera.comTo block a few sites:
!:http://www.google.com !:opera.com !!:^ftp://Blocking on all Google sites, except German and French:
!:http://www.google.com/ ~~:^http://www\.google\.(?:de|fr)Allowing only the "MyOpera" and "LinkedImages" rules here on my.opera.com:

In the meantime, many of the rules were updated too, some of the old ones are not compatible with this version, so if you haven't enabled auto-updating for Sieve, then you need to update it manually.
- Fixed compatibility with Firefox 26+;
- Custom styling, which is actually nothing new, but the styling options now are combined into one input, where multiple CSS properties can be written. The new is, that now it automatically handles different margin, padding and/or border sizes. So now, for example, it's possible to set bigger margin at bottom for browsers that have floating status-bar, so the image can't go under the bar (just like this: "margin-bottom: 30px" or the value you want, also units should be in pixels);
- New "no cover" placement mode for Hz. It tries place the pop-up away from the hovered element, also the placement is static, so it won't follow the cursor, just like in "center" mode. Also a small change to the "cursor at image side" mode, which will now prefer left or right side if there is enough space, instead of putting the image top or bottom;
- Some options in preferences are hidden now by default. To see them, hover the mouse over the right panel (where the Save/Default button is), and tick the Advanced checkbox when it appears.
Known Issues# (vw) Rotated image has incorrect position
# (hz) Rotated image in second full-zoom mode are zoomed always from its center
Some Opera related issues.
It collects the images from the current page and shows them in a slideshow with thumbnails.
Opening it is possible via the Alt+Shift+full-zoom key (Z by default) shortcut or right long-pressing at the top-left corner of the page (50x50px). Pressing Escape closes it.
Beside collecting the image from the page, it can open only the image or images (if it's an album) from the currently visible pop-up.
Extracting frames from animated images
As the title says, it can extract frames from APNG, GIF and WEBP images, also plays them slower/faster forward/backward.
Size limit is 20MiB. The frames are actually canvases, Ctrl+click converts them to actual savable images.
Available through the "Send image to...", customizable at Preferences / Tools:
Extract frames|anim.html?full#%urlRemoving the "?full" parameter will draw the frames as they are stored in the image.
Screen capture (Opera 12.10-12.15)
Go to a random web-page, and press the shortcut (Alt+Shift+T by default, change at Preferences/Tools/Shortcuts) to capture the visible content or Ctrl+Alt+Shift+T to capture the entire page.
Opera can capture only the visible content, means, that the extension must jump all over the page to take shots of every part, which will seem a bit weird, so don't panic, just wait until a new page opens with the captured image (actually canvas), where you can choose the output format (jpeg or png), and then save as.
There are floating elements that are always at the same place on the screen. Normally they would be printed on every frame, but the extension tires to handle them, but it's pretty hard to deal with them correctly, so maybe you won't always get the result that you want.
Other problems you may face with screen capturing:
- plugin-content can't be captured
- it can be used only when page-size is 100%
- you may get interesting results with enabled HWA
- on captured image text doesn't have sub-pixel rendering
- use "Fit to Width" to hide horizontal scrollbars if they're not needed
- dimensions of dynamic pages can change, which will result a somewhat broken image
- you may first scroll down the page to force the dynamically generated content to load
- "default" is the suggested filename when saving (since, sadly, there is no Opera API for saving files)
- the page is re-rendered before capture, so you won't get what you actually see (example)
- it may use pretty much memory on large pages (too long pages cannot be captured (a blank canvas will be shown), since Opera uses memory limit)
