Find an image and copy it to the 'images' folder that was included in your starter files for this course (the starter files were all put in a folder named 'web-programming'). Then add an IMG element below that displays the image. Make sure to set the alt attribute, and you may set the width attribute if you like.

Problem 3

What types of images should be saved as .jpg files, and what types of images should be saved as .png files?

72 ppi, pixles per inch

Problem 5

If you want an image to have a transparent background, what type of image should it be (what file extension would you use)?

Problem 6

What are responsive images?

Responsive images are images that adjust smoothly to different screen sizes and resolutions, ensuring they look good on any device.

Problem 7

Find another image and copy it to the 'images' folder. Then add an IMG element below that displays the image. Make sure to set the width and alt attributes. Turn the image into a link by nesting it within an A element. Clicking on the image should open up google.com in a new browser tab.
