Posting of dynamic URL Images to Instagram via Bulk Scheduler

Posting of dynamic URL Images to Instagram via Bulk Scheduler

Dear Zoho Team,
I am excited to have found an easy to use plugin with Zoho Social to schedule Instagram posts. Everything works perfectly except one thing: I am using the mshot method to take automated browser screenshots of my website. These URL's get refreshed roughly every 48 hours. I am adding the ending .jpg to the URL in order to be able to upload them with the bulk scheduler as the bulk scheduler would not accept the mshots with their native URL. When I upload the mshots (with the ending .jpg) using the scheduler, the mshots of that particular day will be uploaded and not the mshots of the actual posting day, which could be multiple days later.

Is there a way to schedule it that way that the image URL will be checked and used immediately before the image is being uploaded and posted to Instagram, so that the most recent image will appear?

Thank you so much for your help,
Phillipp
