When i upload an image zhenphoto does not optimize the image in the upload.
And then if i upload an image with the admin panel and the image is 1 mega.... could I optimize the image in the upload? IS there a plugin o something to do that or to resize the image in the upload

Someone know if it's possible to resize the original image in the upload moment.
I would like that if i upload a image automatically it was resized to a determinated size and the original photo that is too big was deleted from the server.

Zenphoto does not do resiging on original images, just on images it caches. If you want your original uploades a different size you will need to resize them prior to uploading them.

And it´s possible to delete de original image when this image is in cache or the system need that the original image is in the albums folder.

If you delete the original image it is no longer part of your gallery. However the cache copies are not automatically deleted.
