Images and Video Worksheet

Problem 1

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 2

Why is it important to use small file sizes for images (image files that are small in kilobytes)?

Because the website has to request and load the image so small files will load much quicker

Problem 3

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

Images that need to blend into the page and have a translucent background should be .png because .jpg cannot have a translucent background.

Problem 4

Most web browsers display images at what resolution (how many ppi)?

72 ppi

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)?

.png

Problem 6

What are responsive images?

Images that adjust their size depending on the screen size.

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.

Problem 8

Find a video on YouTube that you like, and embed it into this page.
