every day we will renew hundrads sold items

how many hundreds? 200, 300, 400 or 500? at what photo quality? 640x480, 24bit makes roughly 100kB. That's a lot of data to pass around, when 256 Bytes for each item would be enough to provide a unique identifier to each item you sell in the entire lifetime of your shop.

Sum up the time for taking and postprocessing the photos: you'll miss that at some point.

If you delay processing, you have ~200MB of raw photo data per week, selling 400 items a day, 5 days a week - your hardware shop will thank you for your approach...
