Show Featured Image Size in Admin TopBar

Show Featured Image Size in Admin TopBar | Apasionados, Apasionados del Marketing


This plugin displays the image size for the featured image in the admin top bar. We find this very handy, because you don’t have to look up the default size of the featured image each time you publish a post.

We created this plugin because we manage a large number of blogs with different themes. Normally we always have to check the default size of the featured image before publishing a new post. This means that we have to visit a post published in the past and check the featured image size.

With this plugin you can configure the default featured image size so that it is displayed in the topbar in the administration area.

Easy. Handy. And it saves us a lot of time.

We think it will save a lot of time of everybody that manages blogs with different themes and different default featured image sizes.

Translating WordPress Plugins

The steps involved in translating a plugin are:

  1. Run a tool over the code to produce a POT file (Portable Object Template), simply a list of all localizable text. Our plugins allready havae this POT file in the /languages/ folder.
  2. Use a plain text editor or a special localization tool to generate a translation for each piece of text. This produces a PO file (Portable Object). The only difference between a POT and PO file is that the PO file contains translations.
  3. Compile the PO file to produce a MO file (Machine Object), which can then be used in the theme or plugin.

In order to translate a plugin you will need a special software tool like poEdit, which is a cross-platform graphical tool that is available for Windows, Linux, and Mac OS X.

The naming of your PO and MO files is very important and must match the desired locale. The naming convention is: language_COUNTRY.po and plugins have an additional naming convention whereby the plugin name is added to the filename: pluginname-fr_FR.po

That is, the plugin name name must be the language code followed by an underscore, followed by a code for the country (in uppercase). If the encoding of the file is not UTF-8 then the encoding must be specified.

For example:

  • en_US – US English
  • en_UK – UK English
  • es_ES – Spanish from Spain
  • fr_FR – French from France
  • zh_CN – Simplified Chinese

A list of language codes can be found here, and country codes can be found here. A full list of encoding names can also be found at IANA.
