Thread: Image uploader functions

Image uploader functions

Hi,

I am trying to understand how the ClassiPress image uploader works.

1) My server files get more and more, it looks like the original images are uploaded, scaled and all kept - even the big original file. Is there a way to dump the original file to save server space? (I know there are apps, but would prefer to use that is in the theme)
2) Are images automatically deleted if not in use (or the ad was delted)? e.g. Someone starts to place an ad and then uploads 3 images, but never finishes the ad, so the images become useless. I did that and the image is still on the server. Is it purged over night or stay forever?
3) Uploading multiple images at once would be great. I saw this thread: https://forums.appthemes.com/classip...ploader-86713/
But I wonder if it will be overwritten when an update comes. How to change it in the child theme?
4) The upload of images works fine, but then it takes up to 10sec until the thumbnail pops up. I assume the scaling takes time. How to speed it up? I assume it is connected to my server or the theme?

Thanks a lot.
