The photo gallery allows you to examine the high-resolution photos for each taxon. It is also used for certain other images, e.g. figures used in a glossary.

Note that the photo gallery is only used if JavaScript is enabled in your browser. If JavaScript is disabled, the browser’s default image viewer is used instead.

Here’s an example photo gallery to practice with.

mouse actions

navigation

Click the white arrow on the right or left to switch to the next or previous photo. The arrows only appear if there is more than one photo in the gallery.

To return to the originating page, do any of the following:

zoom

Click anywhere in the image to zoom to fit (the default zoom level). If the image is already zoomed to fit, it instead zooms to the maximum pixel-accurate resolution. (You can zoom closer than this if you want the image to be even bigger.)

Scroll the mouse wheel up or down to zoom in or out. The image zooms toward or away from the point under the mouse cursor.

pan

To move the image, press the mouse button down anywhere within the viewing area and move the mouse while holding the button down. This is particularly useful for viewing other parts of the image while zoomed in.

touch actions

navigation

Tap the white arrow on the right or left to switch to the next or previous photo. The arrows only appear if there is more than one photo in the gallery.

To return to the originating page, do any of the following:

zoom

Tap anywhere in the image to zoom to fit (the default zoom level). If the image is already zoomed to fit, it instead zooms to the maximum pixel-accurate resolution. (You can zoom closer than this if you want the image to be even bigger.)

Touch two fingers to the sensor and drag them away from each other or pinch them together to zoom in or out. The image zooms toward or away from the point between your fingers.

pan

To move the image, touch anywhere within the viewing area and drag your finger across the sensor. This is particularly useful for viewing other parts of the image while zoomed in.

keyboard actions

navigation

Press the right or left arrow key to switch to the next or previous photo. The arrows only appear if there is more than one photo in the gallery.

To return to the originating page, do any of the following:

zoom

Press the space bar or ’Enter’ key to zoom to fit (the default zoom level). If the image is already zoomed to fit, it instead zooms to the maximum pixel-accurate resolution. (You can zoom closer than this if you want the image to be even bigger.)

Press ’Page Up’ or ’Page Down’ to zoom in or out. The image zooms toward or away from the center of the viewing area.

pan

Sorry, there are currently no keys to pan the image.
