The highlights in the screenshot help to show something very important in the screenshot image. You can use free software like GIMP to make highlights on your screenshot image.
Purpose of Applying Highlight Screenshot with GIMP
By applying a Highlight to the screenshot image it will make the image in your article look more professional. People who see the screenshot image will find it easier to find what is very important to do so that your blog readers don't look confused with the screenshots that you attach because readers can easily find marked destinations.
Examples of Highlight Screenshoot Applications
Previously, we tried to make a comparison between the screenshot image that has applied the highlight and hasn't applied the highlight. Try looking for the label in the following image (click for high resolution).

Have you found it, friend? How long does it take to find the word label? Maybe it can be quick for those who are already familiar with blogger layout but it is unlikely for those who don't know blogger layout to find the word label quickly, why? Because there is no sign or highlight which is the most important and which is not important or we call it the highlight.
Now try to find the word "Javascript Fundamentals" in the screenshot image that has been highlighted below, so that my friend is not familiar with the image above, I changed the image to a different image.

Have you found it? How fast? Very fast? I am sure my friend found it in an instant, unless (sorry) there are vision problems in your eyes. Because the part that is marked or highlighted will look different from the others so that the eye immediately focuses on the highlighted image. Wouldn't applying highlights make your blog readers more comfortable?
Why Make Highlights with GIMP?
The reason I use GIMP is free, yes GIMP is an open source software that you are free to use as freely as possible and even change the software itself if you can, of course. In addition, GIMP can be used on all existing Desktop operating systems from Windows, MacOS and Linux. As a Linux user, of course I prefer to use GIMP instead of paid Photoshop software, Photoshop itself is not impossible to install on Linux because there is a way to run Windows applications and games on Linux but I don't want to be complicated and of course prefer open source rather than pirated. In addition, GIMP is lighter than Photoshop and is not large in size to install on your computer.
How to make a highlight on the screenshot image
Now open GIMP, friend, and open the image file that you want to highlight on your picture by accessing the File> Open menu or you can also use a shortcut . Ctrl+O

If you have a screenshot that is already on your clipboard, you can also use the image as a new image by accessing the Edit menu> Paste as> Paste as New Image or using a shortcut . Ctrl+Shift+V

Then select the rectangle tool with shortcut R.

Now, buddy, select the part you want to highlight or highlight on the image.

Now invert the selection by going to Select> Invert and also accessible by Shortcut . Ctrl+I
Because you have used invert, the selected one is not selected and vice versa. Now, please, my friend, select the Paint Brush tool, you can also use the shortcut P, we will use this tool to give a dark color to the parts that are not highlighted.

Tool settings in the Tool Options section with an opacity of 50%, select brushes that have no blur or solid and the size can be adjusted as needed, the opacity function allows parts of the image that are not highlighted to still be read and solid brushes allow us to give a dark color to them. picture. Can see the following picture.

Please apply the brush like a friend scribbling a book on all parts of the image but when you click hold and never let go, click before all the parts that are not highlighted are colored if removed and continued, the new color will be overwritten so that it has 2 layers of color and color. the part that is not highlighted is not neat.
