Overview

Product summary

Review the store description, core capabilities, and common use cases.

*** 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.

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.

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!

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.

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.

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.

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.
