Egg Slip Scanning – PowerShell Workflow

A fast, repeatable process for organizing CZUR scans into JPEG/ and TIFF/ derivatives, with consistent naming and light automation.

---

Folder & Naming Conventions

• Family folder contains one folder per species:

  • Catalogued: Genus_species
  • Not yet catalogued: Genus_species_(uncatalogued)

• Inside each species folder the script creates:

  • JPEG/ – renamed copies for review/renaming
  • TIFF/ – final LZW-compressed TIFFs (from JPEG/)

File naming

• Catalogued placeholder: Genus_species_E01.jpg, Genus_species_E02.jpg, … (2-digit zero-padded)
• Uncatalogued placeholder: Genus_species_Uncatalogued01.jpg, …02.jpg, …
• Later, manually replace E## with the actual catalog number (e.g., E1234), and tag backs as (A) / (B) when needed.

Timestamp extraction

• If original CZUR filenames match YYYY_MM_DD_HH_MM_SS, the script applies that time to the copied file’s Created/Modified timestamps.

---

What the Script Does

File: Process-Images.ps1 (run from a species folder)

1. If JPEG/ does not exist

   • Creates JPEG/
   • Copies all *.jpg in the species folder into JPEG/
   • Applies placeholder names (catalogued = _E##, uncatalogued = _Uncatalogued##)
   • Attempts to set timestamps from original filenames
   • Prints next steps (rename in Explorer, verify against spreadsheet)
   • Stop here (you’ll run the script again later to make TIFFs)

2. If JPEG/ exists and TIFF/ does not

   • Creates TIFF/
   • Converts every JPEG/*.jpg to LZW-compressed .tif in TIFF/
   • Moves your shell to the next species folder (alphabetically) and prints a reminder to run the script again there

3. If both JPEG/ and TIFF/ exist

   • If either contains files: warns you (already processed; double-check)
   • If both are empty: deletes them and re-runs itself (fresh start)

---

One-Time Setup (per Family)

1. Connect the CZUR scanner and open CZUR software.
2. Set storage folder to the Family folder you’re working on.
3. Species folders have been pre-created by the CreateSpeciesFolders script. You should only need to create a folder manually for special cases like Genus_species_(uncatalogued).

---

Scanning Procedure (per Family)

1. Scan the front of each envelope first (as a separator/reference image).

2. Scan slips, front first; scan backs where present (you’ll add (A)/(B) when renaming).

3. For long white envelopes (bulk/overflow):

   • Scan those first; mark their E numbers yellow in the spreadsheet.
   • Copy those images into the correct species folder later.

4. If an envelope already shows initials/“scanned,” still scan the back and front to keep track. Rename folder as:

   • Genus_species - 11SEP25 ERL

5. If a species envelope is missing, create a placeholder folder:

   • Genus_species - Missing

6. At the end of a Family, change CZUR’s storage folder to the next Family.

---

Organizing by Species (before running the script)

1. In Explorer, use the envelope scans to separate species.

2. Copy each species’ slip scans into the matching species folder.

   • Do not copy the envelope scan into the species folder.
   • It may be useful to have the timestamps of when a species was scanned, in case a scan is misplaced.
   • Keep it only as a visual separator for personal reference, don't transfer it to USB drive

3. For long-envelope items, confirm destination via the spreadsheet and place them correctly.

Running the Script & Renaming

1. In Explorer, Shift+Right-click the species folder → Open PowerShell window here.

2. Run:

   ..\..\..\Process-Images.ps1
   

   (You can type ..\..\..\P then press Tab to autocomplete. Use Up Arrow to repeat later.)

3. First run (no JPEG/ yet):

   • Script creates JPEG/ and copies/renames your scans with placeholders.

   • In Explorer:

     • Use Extra large icons + Preview pane to read numbers quickly.
     • Sort by Date → Ascending to keep scan order.
     • Rename E## to the actual catalog number (e.g., E1234).
     • For backs/multipage, name as E1234(A), E1234(B), etc.

4. Spreadsheet check

   • Check off scans; fill in scan date.
   • If something is missing: check the Zeros sheet; re-check envelope (slips can stick); verify numbers; rescan if needed.
   • Rescans: drop into the Family folder, copy into the species folder, then into JPEG/ and rename manually.
   • If still missing, highlight red in the spreadsheet.
   • Consolidate any yellow items (from long envelopes) into the correct species; use another long envelope if needed and include the original small envelope.
   • Reorder physical cards in the envelope to numerical order if needed.

5. Second run (with renamed JPEGs):

   ..\..\..\Process-Images.ps1
   

   • Script makes TIFF/ (LZW) from your JPEG/ files.
   • Automatically advances to the next species folder and prompts you to run it again there.

Tips

• Keep the original CZUR files in the species folder (outside JPEG//TIFF/) for provenance.
• If both JPEG/ and TIFF/ already contain files, the script warns and exits—double-check you’re in the right place.
• If both subfolders exist but are empty, the script deletes them and restarts cleanly.
• If both subfolders exist and have files, the script informs you. Check they are complete, and manually change directory to next species folder.
• If the scanner is working well, it may be best to get as many scans done as possible before renaming.
• If scanner looks out of focus, wiggle the card, or back out of scan mode and reenter it.

Quick Reference

• Catalogued placeholders → Genus_species_E01.jpg → rename to real numbers later.
• Uncatalogued placeholders → Genus_species_(uncatalogued) folder → Genus_species_Uncatalogued01.jpg, etc.
• Backs/multipage → append (A), (B).
• Run order: create JPEG/ → rename → create TIFF/.
• The script then moves you to the next species automatically.
