Wiki.GIS.com:Options to not see an image

Some people wish to not see some images on wiki.gis.com, for various reasons – images may not be suitable for a work environment; they may wish to prevent their children from seeing such images; their religion may forbid it; and so on.

wiki.gis.com is not censored, and the community will in general not be prepared to remove content on grounds of being objectionable to some people. wiki.gis.com will also not use specific disclaimers within articles warning readers of such content. All articles fall under the site-wide Content disclaimer. However, readers who do not wish to be exposed to certain content have a number of options to selectively prevent wiki.gis.com content from being displayed on their screen.

This page assumes that (a) you still want to visit wiki.gis.com (rather than creating a fork or simply staying away) and (b) you do not wish to enter discussions within wiki.gis.com policy to have the image changed, removed or  deleted by building consensus.

wiki.gis.com readers have two possibilities to influence the way wiki.gis.com content is displayed on their screens:
 * 1) by creating an account and reading wiki.gis.com while logged in. User accounts offer a number of preference settings, including the selective display of images.
 * 2) by filtering content locally, either by setting up a proxy (such as Privoxy), or by configuring their web browser (including the possibility to display no images at all).

wiki.gis.com user preferences
To disable the display of images for a specific article, or for all articles on the "bad image" list, you must have an account. If you do not have an account, visit Special:Userlogin to create one.

Specific pages
Once you have an account, you can disable the images on a specific page by changing your personal settings at your CSS page. This allows you to avoid images that offend you without affecting other users. To do this, create a page at Special:Mypage/monobook.css and add the following line:

e.g.

All "bad images"
MediaWiki:Bad image list restricts specified images from being seen except on its image page and certain articles. It is possible to prevent these images from being viewed at all by changing your account's javascript page. See User:Mr.Z-man/badimages for details.

Note that this has limited utility as images are added to the bad image list because of concerns about disruptive use and vandalism, not because someone finds the image objectionable. Many images that some readers may find objectionable are not eligible for the list.

Other possibilities
If you are unhappy with the configuration possibilities available at present, you may consider submitting a code change for the copyleft MediaWiki (which displays wiki.gis.com's content). The Wikimedia Foundation, which provides the hosting and bandwidth for wiki.gis.com, lacks resources to implement many good and useful modifications to the software that displays wiki.gis.com's content. Such modifications can be created and submitted to the Foundation for addition to MediaWiki. An example of what could be created is a user option to not display images that are in certain categories.

Use a proxy filter
You can selectively block content by using a web filter program. Freely available examples include Privoxy, SafeSquid and DansGuardian. Once you have installed such a program, you can exert fine-grained control over what content is received by your web browser.

Mozilla Firefox 2.0

 * either: right-click the example image to the right and select "Block Images from upload.wikimedia.org"
 * or: select Edit/Preferences and in the Content tab click on "Exceptions" next to "Load images automatically". In the popup window, type "wikimedia.org" and click "Block".

Opera 9.0

 * Right-click on the page, select "Block content...", and click on the image(s). If you only want to (un)block a particular image, and not all images from the same source, hold the shift key while (un)blocking.
 * Click "Done"

Without add-on

 * 1) On Windows, select the "Tools" menu, on Mac OSX, select the "Firefox" menu, or on Linux select the "Edit" menu.
 * 2) Select "Options" on Windows, or "Preferences" on Mac OSX and Linux
 * 3) Click the "Content" tab.
 * 4) Uncheck the checkbox "Load images automatically."

With add-on
https://addons.mozilla.org/en-US/firefox/addon/232 allows you to add a button to the Firefox tool bar that toggles images on and off.

Other Mozilla-based browsers
The Firefox 2.0 instructions may not work on all browsers in the Mozilla family (such as the GNOME web browser Epiphany). In that case, enter about:config in the location box, and change permissions.default.image to 2 to disable image downloads. To restore the default behavior, change it back to 1.

Opera
View->Images->No Images

Or

Right click->Block content->click content wished to be blocked

Internet Explorer 7

 * 1) Click the "Tools" button.
 * 2) Select "Internet Options".
 * 3) Click the "Advanced" tab.
 * 4) Scroll down to "Multimedia" and uncheck "Show pictures".

Safari 3

 * 1) On Mac OSX, select the "Safari" menu.
 * 2) Click "Preferences".
 * 3) Click on the "Appearance" button.
 * 4) Uncheck "Display images when the page opens."

Install the Adblock plugin (Mozilla)
Open Preferences and click the "Manage Add-Ons" button in the "Main" Tab. Select and install the "Adblock Plus: Element Hiding Helper". After restarting your browser, you have a menu labelled with an "ABP" icon in the top right of your browser window. From this menu, you can define precisely what content should be suppressed by your browser.

Do not use a predefined filterset, which may be configured to allow (whitelist) all Wikimedia content. Alternatively, use the "open blockable items" option to review whitelisted content on the current page, and disable filter rules as desired.

To block a specific image, right-click on it and select "Adblock image" from the context menu. For example, right-clicking on the top image at Penis, you get the option to block " http://upload.wikimedia.org/wiki.gis.com/en/thumb/1/1d/Labelled_bw_flaccid_penis.jpg/* ". This will block all scaled-down versions of File:Labelled_bw_flaccid_penis.jpg. If you want to filter all images containing "penis" as part of the filename, use the rule " http://upload.wikimedia.org/*penis* ".

Once you have defined a filterset, you can distribute it to interested parties sharing your content preferences.
