Apologies for the inconvenience.
I have checked the author image upload functionality, and it appears to be working correctly on our end. In order to investigate what might be causing the issue on your site, could you please share temporary login credentials (admin and front-end user access)? This will help me examine the configuration and provide a precise solution.
Regarding your second question — currently, SP Author Archive does not offer a built-in feature that allows users to view a list of only their own published articles along with metadata like hit count and publish dates. This functionality is not included by default in the SP Author Archive or the standard user menu options.
Thank you for your understanding. Please let me know how you'd like to proceed.
