[Accessibility] Links don't have discernible text

[nwanduka]

Some image links on the Home Page don't have discernible text. This is not following the WCAG 2.1 Standard regarding links. These links are inaccessible to these users, especially those who rely exclusively on a keyboard (and no mouse) to navigate a webpage.

To Reproduce
Steps to reproduce the behavior:

1. Right-click on the home page and click inspect to open the dev tools window
2. If you have the Axe extension installed, open it and run an accessibility test
3. One of the accessibility issues discovered is that "links must have discernible text"

Expected behavior
According to the WCAG 2.1 standard, link text and alternate text for images, when used as links, must be discernible by a screen reader, must not have a duplicate label, and must be focusable.
