The open source Gnu Image Manipulation Program, otherwise known as “GIMP,” competes with high-end image editing software, such as Adobe Photoshop, when comparing features and tools. If you have a saved copy of your Twitter logo picture on your computer, you can use GIMP to resize the avatar to a specific size. Once you have resized the image, you can then re-upload image to Twitter to use as your profile photo. Twitter avatars are automatically resized to 48 x 48. To retain the quality of your image, resize the photo to match these dimensions.

Resize Image

Step 1

Right-click on the photo file that you use as your Twitter avatar, then click “Open With.” Click “GIMP” to open the photo in the GIMP application.

Step 2

Click the “Image” option in the top navigation menu, then click “Scale Image” to open the Scale Image dialog box.

Step 3

Delete the characters in the “Width” field, then type the desired width for the resized image. The height changes proportionally to the width as long as the Chain icon is intact. To unlink the Height and Width fields so you can edit the dimensions independently, click the “Chain” icon. The Chain icon changes to a broken link. Delete the characters in the “Height” field, then type the desired height for the resized image. Note that changing these values independent of one another can result in a distorted image.

Step 4

Click the “Scale” button. The image resizes to your specifications.

Step 5

Click the “File” option in the top navigation menu, then click “Save” to save the image with the original file name and format. Click “Save As,” then select a different file format from the File Type drop-down box, if desired. Click”Save” to save the file.

Upload to Twitter

Step 1

Log in to Twitter, then click the gear icon to open the Settings menu, then click the “Profile” tab.

Step 2

Click the “Change Photo” option next to your current avatar, then click the “Upload a Photo” option. Browse to the resized photo on your hard drive, then click “Open.” The photo uploads to Twitter.

Step 3

Click “Apply.” The resized photo is applied as your Twitter profile photo and a confirmation message is displayed.
