Description from store

*** Configuration ***

At first, don't forget to set a limit mode and value in the Options of the extension.

*** Usage & Hotkeys ***

Use Ctrl + mouse move over image for load the original instance.

Note that, a host settings (limit mode and value) restores after browser reloading, but the on/off states of tabs does't.

If you want to see only small images(like icons) but cut off the big, then set image data size between 1K - 5K.

*** Known issues ***

1.On some sites the image fully loading(Ctrl + Mouseover) not working well. It depends on how site was built. I have fixed many issues but I guess that is not all.
2.On some sites a limitation of the image data size is not working. Images loads fully. It happens when a server ignores specific parameter in the request.

*** Release notes ***

2.1
- Fix showing on popup host without ".tld".
- All net request rules are session now to fixed order of execution.
- Fix reload original image after the first load error.

2.0
- First major release.

All the best!

Pilot Man 2024-10-29: This extension is well-suited for Manifest V3, which seems to be the only system it currently supports. Previously, controlling any website was more straightforward, but now we need to rely on headers for this purpose. The main concern with this approach is that certain websites may not function as expected, especially if they don't support adding headers. I didn't added another star because description and title doesn't fit well for it.

javad mnjd 2023-05-06: It's a very good extension, but without ability to save settings across restarts It is very annoying. only if it could remember the settings per website after restart it would be great!

Pat MySecret 2022-12-19: Best for someone limiting data usage. For simple image on/off, there's a different extension called "Block Image". Tunable Image Block filters by image data (vs pixelated) size Larger images can be off while retaining page sense.. possibly saving toggling on/off.. then again, some images appear partially. If you toggle it off, data setting tends to get lost. Workaround: install the "Block Image" extension as a toggle & be able to keep your setting for on mode. leaves an image frame outline. the space can be adjusted light/dark. doesn't block icons. It becomes difficult to get images back on, so I'm inclined to go with something else. I'd prefer an extension that blocks by pixel size.

Ofek Aizik 2022-07-08: Good but not perfect, its great that it can selectively choose what to show but the implementation of "ctrl hover" to show the image is less than ideal on sites with alot of picutres. The extension also breaks when it is used with the Bandwidth hero extension.

Kyoto Kyoto 2021-06-13: Хорошее расширение! Единственное замечание: как я понял, расширение (в некоторых случаях, и которые в 99% не должны случаться) отправляет данные через API https://images.weserv.nl/?url= , чем снижает приватность пользователя. Сервис имеет открытые исходники на github, и тем не менее, неплохо бы добавить опцию отключения. Это API, насколько я правильно понял, используется при нажатии на Ctrl и клике на картинку, чтобы сжать через этот сервис и загрузить облегченную версию картинки, пожатую в base64. UPD: Это происходит только если картинка по какой-либо причине не загрузилась (ошибка), чтобы подгрузить через стороннее API, как fallback. (Но я бы всё же вывел это в опцию) ==== Очень элегантно придумано: отлавливать картинки по Content-Length на этапе получения заголовков. Магия! ==== Nice extension! The only note: as I understand, the extension sends data (in rare cases, which in 99% must not occur) via the API https://images.weserv.nl/?url=, which reduces the end user's privacy. This service is open sourced on github, but nevertheless, it would be nice to add a "disable" option. As far as I understand, this API activated only when pressing "Ctrl" and clicking on a pic, and original image is faield to load (so it loads a lighter version of the image, in base64 format) ** This happens only if an img has not been loaded for whatever reason (an error occured), so it tries to load it from external API (sources are open), as a fallback. But I'd rather offered this through an option.

asn1k li 2020-04-07: Great extension! Useful when suffering a slow connection. It would be better if it can display a default image (white or grey) with the alt words of the <img> in it. The default 'no image' icon doesn't looks kind of crappy.

Drakulian 2018-02-06: Doesn't work at all. Doesn't have any option for "tuning" either. The whole idea is that I may want to disable a single image on a page, not all images. Either way this thing doesn't block anything making it useless.

Anonymous 2017-12-19: Very efficient, but I would need a white list. Filtering on the domain, or per site, rather than per size.

Albert911emt - 2017-11-12: This app really does block images, and it works well. But it does not remember on what sites to block images and what sites not to. So when I shut down Chrome, and come back to it later, I have to unblock the same sites all over again. This app seriously needs a "white list" option, badly.

saeed serpooshan 2017-06-13: Very interesting! I need such tool to control my traffic/bandwidth usage. When pics are larger than your desired size, they load partially up to that limit. This way, you can see a partial/preview of images as most jpg's are saved as 'progressive' type. I'm just looking for an option to be able to load images which are already in cache (firefox has some add-ons named imgLikeOpera but it doesn't work for recent versions).

Moss Doerksen 2017-05-17: Looks like it can save me a lot of bandwidth. Works pretty well, but sometimes it is buggy or confusing in it's behaviour. I don't know. I am still trying to fully understand how it works. Some problems might be related to my crappy internet.

Martin RW 2017-04-27: Seems good. But please add option to whitelist some pages, or have ability to set different image filtering options for different websites. If this option exists, it will be 5 star from me.

Viketo Sumi 2017-03-08: It is awesome. Thank You very much. I have been able to save up-to 95% of data. I configured its default size to 5% but sometimes have the need to upgrade to 40% for some webpages to display to display its complete contents. Keep it up!

Игорь В 2017-03-06: Расширение отличное, но: 1. Не блокирует картинки здесь, в магазине расширений Хром, значит сайт занесен в "белый список", а самостоятельно отрегулировать это невозможно (?) 2. Если задать поиск в Гугле, то обратим внимание на картинки, они все равно загрузятся, штук 10-15 из числа первых Кажется, проблема все же в наличии каких-то встроенных фильтров, внесенных в белый список, так как на некоторых сайтах на главной странице картинки блокируются, а при переходе по внутренним же ссылкам, картинки показываются. Денис, пожалуйста, усовершенствуйте свое расширение
Alfredo B Bear-Lacis 2017-02-14: 1. Not available on site-by-site. 2. Shift-mouseover or Ctrl-mouseover didn't work.
Sadegh Jafarnejad 2017-01-03: great extension especially for limited bandwidth..best one compare to opera cache image and other image blockers. it would be great if the developers add a feature of image quality. anyway, thanks for this one

mark ifi 2016-12-28: this is the proper way to do this. better than the built in image block of Chrome, and even better than the one in Opera.

Ilya Ushakov 2016-03-23: Awesome! This really significantly reduces a traffic. Besides, this is important for me, that images have a real width/height and the page layout is not skewed.
