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)?

Helps with the speed of loading the page especially when users are utilizing smartphones.

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 do not support transparent backgrounds whereas .png does. .jpg files do not blend into webpages with different background colors.
.jpg is good for actual pictures and .png is better for graphics (ex: logo).

Problem 4

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

Standard is 72 ppi (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 adjusts to different screen sizes so that it looks good on any(most) devices.

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
