i have 50GB of images in internal-data/attachment folder and i want to save server disk space.
i resize the attachments using windows resizer (fast-stone image)
-rename .data to .jpg
-resize all images to 800x600
-rename back .jpg to .data
my question is:
once i reuploaded the .data file attachments in internal-data folder
How can i rebuild the attachments (not thumbnail) to fix the attachments pictures ?
