Restore Images after delete

I was doing an upgrade from 5.7 to 5.8 but I had to delete all the images from the file manager to do this upgrade (The website wasn't upgrading unless I delete all the images)

Is there a way to restore 1000 deleted images after I upgraded?

I did and uploaded the 1000 images again, but after I uploaded them they don't appear in their places in the website, probably because they are uploaded in a different folder.

Is there a way to restore them so they will be in their places again?

I have a backup of the website and the database before I upgraded.

Could this be done?

I suspect that, when you delete an image using the File Manager (which is the right way to do it), any references to that image (eg, in Image blocks) are also removed (as they should be). Therefore, simply re-uploading the images won't make them reappear in their original locations.

There is currently work being done on image-related stuff in the current development branch of c5:
It's *possible* that these changes, when released, would allow a 5.7-to-8 upgrade to work without the need for you to delete the files. You could decide to wait and see (ie, not work on your current 8 installation), or even participate in testing the develop branch (when they sort out the upgrade aspects).

In either case, I'd recommend keeping those backups!

Thank you very much I understand that now, so the problem that I can't upgrade without deleting all the files first isn't only my problem? is this an issue in the version 8 itself? because lately I've been trying a lot of stuff to upgrade without deleting the images but nothing is working.

I haven't been following the changes to c5 closely enough to know for sure. I've just upgraded six sites from to 8.2.1 and they all went through fine. However, I didn't have a huge number of images, nor any especially large images.

But all currently-released versions of c5 8 can mishandle image thumnailing/resizing in some circumstances. I don't know whether this affects the upgrade process but it's possible.

It would be helpful if you could identify what types of images cause upgrade problems. Possibilities are certain file types (PNG, SVG), large file sizes, or large megapixel sizes. I know that's a lot of work and probably not worthwhile.
