Galleries based on the <gallery> Tag

For other solutions to display galleries see: Galleries

An assistant to build and insert wikicode for image galleries based on the HTML <gallery> tag.

Galleries based on the <gallery> tag are series of images obtained enclosing the filenames between the HTML tags <gallery>...</gallery>. This is the easiest method to display galleries in Wikipedia articles. Although there are several methods to build galleries using the gallery tag, this assistant does not cover all of them, but only a selection of four methods.

This assistant helps you to build and insert image galleries using the HTML gallery tag, even if you ignore the sintax. With this technique the number of images in each row adjusts automatically to the page width. Those images which have not enough space in a row, flow automatically to the following row. Although some galleries may be aligned to the left the subsequent text cannot float on the other side of the page as happen with other techniques.

How to use this assistant

Select the method you want to use to build the gallery and make the changes you want in the image dimensions:

· Enter gallery data:

· Name of the image file (required), not the entire URL

· Footnote (recommended); and

· Alternative text (optional).

· Include all the images you want. These data will be saved after closing the assistant.

You can generate the gallery code clicking on the command button <Generate code>. The generated code is NOT saved when you close the assistant. But, if an error occurs during insertion, the generated code is saved until the next opening of the assistant, unless you close the Edit window or leave the application.

· If you know the sintax, make links and format changes directly in the code window.

· Insert the gallery clicking on the command button <Insert gallery>.

· To erase data and build a new gallery, click first on the command button <Blank gallery>.

The assistant offers several methods to build image galleries based on the HTML <gallery> tag.

1. Traditional method

This method renders rows of four images arranged horizontally in boxes of fixed size, with a very light background color. The resulting galleries are quite similar to those based on tables. The boxes are surrounded by a thin grey border. Default size of the images is 120 x 120 px, but you can optionally increase this size to 180 x 160 px. If you want even bigger dimensions you should then change manually the figures directly in the code window. Galleries of this type, align to the left by default, but you can change the alignment manually in the code window.

As the size of the images are limited by the size of the boxes, this method renders images with different heights, what is more evident when the images have different aspect ratios. You can solve this if you gather images with a relatively similar aspect ratio. The footnotes appear aligned to the left by default.

2. No frames method

This method renders rows of images without frames, so the gallery is more compact. There is less padding, and therefore the images are closer to each other, although some space between images is still wasted. As occurs with the traditional method, this method renders images with different heights.

3. Compact method

This is the default method. It renders galleries centered in the page, without any space wasted among images. All the images are displayed with the same height. The default height is 125 px, but you can increase it up to 160 px to show bigger images in the same space. If you want to increase this value, you can do it manually in the code window.

4. Slideshow method

This method uses a combination of the <gallery> tag with table code. The gallery consists of a table aligned to the left with a single cell containing the image gallery. It produces an special type of gallery showing all the images within the same frame, but one at a time. Just over the frame there are buttons that allow to switch images.

This method is convenient for big images, because makes the best use of the page space. The assistant gives a default width of 350 px for the images. If you want to modify this value you can do it directly in the code window. The "alt" text is not considered by this method.
