Hi @sajarac,
Do you want to see these pictures (that you saved within your SP list) within your MS Access linked report?
Based on the screenshot that you provided, I found that you have saved the data URL of the pictures captured via the Camera control within your app into your SP list.
If you want to see these pictures (that you saved within your SP list) within your MS Access linked report, I afraid that there is no way to achieve your needs currently.
The Data URL (that you saved within your SP list) is the base64 representation of the picture captured via the Camera control within your app, so you could not see these pictures within your MS Access directly.
As an alternative solution, you could consider take a try to save these captured pictures (captured via the Camera control) into a SP library (Or other cloud storage, e.g. OneDrive for Business) as image files rather than image Data URL. Then within your MS Access linked report, you could add the link to the image files stored within your SP library to reference the picture files.
More details about uploading images (captured via the Camera control) into SP library, please check the following blog:
