Uploading tiff files in zenphoto gallery

Use some photo editing software… resizing images is really nothing that specific…

Hello,
I wrote a script to convert my tiff files to jpeg files.
I am just wandering if there is a risk to lose some resolution.
Here is my script:

!/bin/bash

for f in $(find -name *.tif); do echo "Converting $f"; convert "$f" "$(basename "$f" .tif).jpg"; done

for f in *.tif; do echo "Converting $f"; convert "$f" "$(basename "$f" .tif).jpg"; done
mv *.jpg ../JPG/.

assuming the script is in my TIF directory and that ../JPG exists.
For Exemple:
/home/giuseppe/TIF ( tif files location)
/home/giuseppe/JPG ( jpg files location)

I thing this way I have a solution concerning my old tif files.

Best Regards.

If you don't change the resolution, you would not loose it. I don't think that your script does that but I am not familar with the scrip tlanguage you used. But you might loose quality as jpg is generally lossy compress while tiff is not.

Do you mean, I loose some quality and I have less compression ?

Not necessary, jpeg has smaller files but lossy compression if compressed. An uncompressed jpeg is bascially as good as a tiff. But the point of using jpgs is compression to get smaller files.

Hello,
That's fine. Then it is not an error to convert all my old Tif files to jpg files and delete the old tif files keeping only the new jpg files that I will load in my zenphoto database.

Best Regards.

If these are important images I would probably keep the original tiffs locally.
