The image naming guidelines are to give documentation contributors a set guidelines about naming an uploaded image file not used by Joomla! Help screens. These guidelines are not absolute but for informative purposes. They should only be used as a reference for helping contributors form a good image file name. Naming an image for use in Joomla documentation is not difficult once you understand how the images are processed and stored. Some of the benefits of Mediawiki's method of image storage are an image history, extra image data, and easy image updating.
The Mediawiki software allows uploaded images to be named by two methods.
Of the two methods, the later method is the easiest method to use.
Image names should consist of an underscore or hyphenated separated list of descriptive words. Think of them as a summary description of the image.
It would be very beneficial if the first part of any Joomla image refers to it's version. This allows someone to instantly know what version of Joomla is connected to the image. Example:
j25. There is no need to insert the .(dot) in the version, please omit it.
<jver>-<admin>-<view>.<extension('png' | 'jpg' | 'jpeg' | 'gif')>
A screenshot of Joomla 3.x or 2.5 administrator's view of the article manager could be written as:
A screenshot of Joomla 3.x or 2.5 site's(frontend) view of the log in module could be written as:
Common sense and a descriptive summary should be the guide for non-Joomla images. Again, use the underscore _ or hyphen - to separate the summary. For images of people, please use the person's name. For images of software or website's, please include them within reason.
GitHub pull request, the Firefox Firebug tool, or these other examples could be written as:
github-pull-request-how-to.png eclipse_indigo_interface_egit_browsing_veiw.png joomla-event-Nov-2013-John-Smith.png firefox_addon_firebug_colour_picker.png
They are short, descriptive and inform the viewer looking at the image call what the image is quickly.
In preparation for documentation localisation, how to address images of different languages needs to be addressed. As documentation becomes localised, it is necessary to let user's and the Documentation Working Group identify images in another language quickly. Please do not use a native language as a file name description. Instead, add a trailing two-letter language code to the end of your file description before you upload the image in the 'base' language description.
Here is the base examples:
<jver>-<admin>-<view>-<language code>.<extension('png' | 'jpg' | 'jpeg' | 'gif')>
Taking some of the examples from above:
