Keep SKU identifiers intact when batch-renaming product images
Use a small mapping sheet to keep product identifiers, leading zeros and image variants understandable when preparing a batch of renamed product photos.
Separate a product identifier from an export sequence
A filename such as product-001.jpg is convenient for sorting a batch, but the number 001 does not necessarily identify the product shown. If you later mix two export batches, identical sequence numbers can refer to different products. This becomes a practical problem when product photos need to match a catalog, a spreadsheet or promotional copy.
Before renaming, decide which part of a filename identifies the product and which part identifies the image view or export order. Keep those meanings separate. A short mapping sheet is often enough; you do not need a large inventory system to avoid losing the connection between a source photo and its output.
Write down a mapping before changing names
Consider a product whose internal identifier is 00427, with front, side and detail photos. Record the exact identifier as text, the original filename, the view, and the intended output filename. For example, the front photo might become 00427-front.jpg while the detail photo becomes 00427-detail.jpg.
If you use a spreadsheet, set identifier fields to text before entering values that contain leading zeros. Check the saved file again after opening it. A product code is a label, not a quantity: turning 00427 into 427 can break a match even though the numbers look equivalent.
Choose a naming approach that matches the tool
The 0UB Batch image studio can apply a filename prefix and generate a sequence. That can be useful for one clearly defined group, such as a set of photos for a single product. It should not be treated as an automatic reader of SKU data or a guarantee that spreadsheet rows will be matched to images.
For a mixed folder, separate products into smaller working groups or retain understandable source names where the workflow allows it. If you need exact identifier-and-view filenames, prepare or rename working copies deliberately and verify the exported names. Do not infer a product match from the position of a thumbnail alone.
Check a three-file sample first
Start with one front photo, one detail photo, and one photo from another product. Export them and compare the downloaded filenames with your mapping sheet. Open each image to confirm the subject, not just the name. Include a leading-zero identifier in this small test if your catalog uses them.
If you download a ZIP, extract it into a new folder before reviewing it. Check for duplicate names, automatic suffixes and overwritten files. Keep originals separate from exports so that a failed naming experiment cannot destroy the only useful reference for the product.
Verify the handoff against the destination
Before sending the folder to a colleague or using it in another tool, confirm that each intended output exists and corresponds to the right product and view. Check the expected number of images per product and identify any missing or extra files. Keep a copy of the mapping sheet beside the exports when it will help the recipient.
When a later workflow uses CSV image filenames, the names in that CSV must match the actual selected files according to that workflow's rules. Stable SKU text, clear view labels and a reviewed sample reduce guessing. Sequence numbers remain useful, but only when the product association stays visible.
