Image Post creation improvements

It is always a bit of a chore when creating a new gallery for one of my Loras. I understand this is not much of an issue for a reviewer or the random user who only adds 1 or 2 images but it is very annoying for creators. It would be really useful to have the following improvements:

1. Uploaded image counter. So you can easily see how many more images you can add.

2. Failed upload status indicator for each image with a retry button. I often select the 20 images at once only for the page to become stuck and appear to be processing. The only indicator that something is wrong is the sorting button being disabled. I then have to refresh the page and some of the images mysteriously disappear making me have to dig once again through my sample images to see which of the 20 images is missing. In my workflow I generate XYZ plots with 16 images per outfit per LORA so digging through the sample images for missing images is a bit of a chore when the gallery eats random ones.

3. Expose the delete button, as this is creation and not edition there's no possibility of data loss. Instead I want to be able to easily and quickly swap an image when I find a defect on it or more commonly when it doesn't pass the "sexy outfit" test by the autotagger and I need one image without it to be the thumbnail.
