How to Manage the Photo Gallery on an Android Phone
You can start the Gallery app on your Android phone by locating its icon, either on the Home screen or the App menu. How the Gallery looks varies from phone to phone, but generally the images are organized by albums, or piles that will look something like the following figure. Choosing a pile displays a scrolling list of thumbnail images. Touch a thumbnail to see the individual full-screen image.
Videos appear in Full-Screen mode, but with the Play button superimposed. Touch the Play button to view the video. Other video controls may also appear on the screen, which let you pause, fast-forward, or adjust the video playback.
Press the Back soft button to back out of viewing an image and return to the album. Likewise, press the Back soft button to return to the main Gallery library screen after you’re done viewing an album.
Many albums are automatically created for you. The Gallery app may also allow you to create your own albums to further organize your media. You can create a new album by choosing the New Album (or similar) command after pressing the Menu soft button. You might also be able to create an album by long-pressing an image and choosing the Add to Album command.
Editing images in the Android phone Gallery
The best tool for image editing is a computer amply equipped with photo-editing software, such as Photoshop or one of its less expensive alternatives. Even so, it’s possible to use the Gallery app to perform some minor photo surgery. Two popular tasks are cropping and rotating.
To crop an image, which is to remove a portion of the image to concentrate on a specific part, heed these steps:
Open the Gallery app, and display the image you want to crop.
Press the Menu soft button and choose Edit.
Choose the Crop command from the Edit menu.
For an alternative, you may have to long-press the image and choose Edit and then Crop.
Use the onscreen controls to crop the image.
The controls you see on your screen may be subtly different.
Touch the Save button to crop the image.
The image’s size and content are changed immediately.
Some versions of the Gallery app automatically recognize human faces. It’s possible to touch a face in an image when using the crop tool and have it automatically frame the person’s face.
You cannot undo a crop.
To rotate an image clockwise or counterclockwise, follow these steps:
Display the image in the Gallery app.
Press the Menu soft button, and then choose Edit and then Rotate.
Or you may have to long-press the image, choose the Edit command, and then choose a specific Rotate command.
In some cases, a gizmo appears on the screen, which you control to rotate the image. You may also have to touch either the Apply or Save button when you’re done rotating.
Not all images can be rotated, such as images synchronized from web albums or social networking sites.
Deleting an image or a video from the Android phone Gallery
To prune media that you no longer want in the Gallery, summon it on the screen by itself. Press the Menu soft button and choose the Delete command. Or, alternatively, long-press the image and choose the Delete command.
You’re prompted before the image is removed; touch the OK button to delete the image. It’s gone.
There’s no way to undelete an image you’ve removed from the Gallery.
Some images cannot be edited, such as images brought in from social networking sites or from online photo-sharing albums.
