Step 3: Select Resize on the drop-down menu.

Step 4: A pop-up window appears. Select one of the three preset sizes (shown on the left). Otherwise, choose Define custom dimensions for a specific size. Another pop-up window appears (shown on the right).

Step 5: To keep the aspect ratio, select the box next to Maintain aspect ratio.

As you enter a number into one of the boxes, the other box will automatically adjust its number in proportion to the number you just entered. If the aspect ratio doesn’t matter, don’t check the box, and enter the numbers in both boxes.

After social media ban, AI bans could be next for school kids
Norway is restricting AI in schools, and other countries could follow
Generative AI

Artificial intelligence is rapidly becoming part of everyday life, and that includes classrooms. Students are turning to tools like ChatGPT for homework, research, writing assistance, and even basic questions. But a growing number of educators, researchers, and policymakers are questioning whether introducing children to AI at such a young age could do more harm than good.

Norway appears to agree. The country has announced a near-total ban on generative AI tools for elementary school students, arguing that children need to develop fundamental reading, writing, and math skills without relying on AI. The move could become an early sign of a broader trend, especially as governments around the world take a tougher stance on children's use of technology.

A wave of new apps marketed on TikTok and YouTube is making it nearly impossible for teachers to tell whether students are actually writing their own homework or offloading it to AI. The New York Times reports that tools known as humanizers and autotypers have closed the gap that used to give AI-written homework away, and that the same companies selling detection software are sometimes the ones helping students get around it.
