Using Images as Data Source for a Simple Agent in Google Drive

Hi, I'm trying to build a very simple agent as a POC that would answer basic questions based on a Google Drive folder that contains personal info: old payslips, P60s, work contracts and a photo of my passport. When connecting with the Google Drive folder, the jpg of the passport photo isn't listed. Are images ignored? Any ways that I could use images as data source to an agent? I know we can upload an image to a conversation. Thanks in advance
