Validation Output Error

Hi,
I was checking the validation of the output for this theme (which I use) because I ran into an error linking my blog to Bloglovin. They suggested I use validator.w3.org to check the validity, and when I did, I ran into this error:

Error Line 275, Column 211: An img element must have an alt attribute, except under certain conditions. For details, consult guidance on providing text alternatives for images.

This error is in the “Sugar & Spice: About” widget but I can’t figure out how to go in the coding and change it.

Can you help me fix this?

(Here’s the link to the markup validation)
