How to find out if image has black borders?

ph flag

On Ubuntu 22.04, I'm trying to find a solution for finding out if an image has a black border around it. On Windows, I used to use MS Office Picture Manager. When an image is opened up in Picture Manager, it happens to have a creamy background with the entire image in the foreground: enter image description here

But when an image is opened on Ubuntu, either with Image Viewer or with Shotwell, it has a black background, with the image in foreground so like this: enter image description here

This makes it impossible to tell if the image has black borders that I may want to crop out.

Any help is appreciated.

Tried changing the "Background Color" in the preferences of the image viewer ?

In the "Preferences" of Image Viewer, there is an option to change the background to a different color. Shotwell does not have an option to specifically change the image background. It follows the system theme. Here, if you disable "Use dark theme" in the preferences,you will see the pictures on a light gray background.

Just tried it and it does solve 50% of my problem. Could not find any such preferences in Shotwell, only Image Viewer, am I missing something?

@vanadlum thanks for the updated answer, appreciate your effort. I am gonna use this until i find a cropping software with different background. (Have GIMP installed so probably gonna try using that first).

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
