[HACKTOBERFEST] Fix missing profile images for some professors on Professors page

[rajeev-sr]

On the Professors page, several professor cards are displayed without profile images (showing only initials instead of actual photos). This creates inconsistency in the UI and makes it harder to identify professors visually.

1.Steps to Reproduce:

2.Go to the /professors page.

3.Scroll through the professor list.

Observe that some professor cards have images, while others only display initials.
