Hi,
I'm RK and I can build you a Desktop App that allows you to select multiple images at once, uploads them as individual posts and sets their title as the file name. It also allows you to set the posts to be published on future dates and times.
1. Upload hundreds of images at once.
2. Can set future dates and times.
3. Post name can be file-name or custom set.
Any other customizations you need can be added. Plus, it's better to have a desktop app, rather than a plugin if you intend to upload in bulk ( hundreds or thousands of images per day).
I can complete and deliver within 12 hours.
Hoping for a positive response.
RK.
