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)?

Larger image files take longer to load on a webpage, which can significantly impact website speed, user experience, and even search engine ranking.

Problem 3

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

JPG files are for less complex images that use lossy compression which makes them ideal for storing and sharing images on the internet or email.
PNG files are more complex and have a larger file size, they keep their details, and allow for transparency on images.

Problem 4

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

72 pixels 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)?

.PNG

Problem 6

What are responsive images?

An image that conforms to the width and height of a webpage / device while maintaining its aspect ratio.

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.
