Troubleshooting and FAQ
Answers to the problems merchants hit most often when changing images in bulk.
Some of my images were skipped. Did something go wrong?
No. A skip means the image already matched your settings, so there was nothing to change. Rewriting it would cost you money and gain you nothing. Skipped images are listed in the run so you can see exactly which ones they were, and they are never charged.
Will my colours change?
No. Every image is written as standard sRGB with its colour profile kept, which is what browsers expect. Photos supplied in a wide-gamut or print colour space are converted properly rather than having their profile thrown away, so a rich green stays a rich green. Check the preview before a large run if you have colour-critical product photography.
Can I undo a run after I have looked at my storefront?
Yes. Every original is kept for 30 days. Open History and restore the whole run, or just the one image you are unhappy with. After 30 days the backup is removed and History shows the run as expired.
A large run is taking a while. Do I have to leave the app open?
No. Runs happen on our servers, not in your browser. Close the app, close the tab, carry on with your day. Progress is on the dashboard whenever you come back. A big catalogue is worked through steadily so that Shopify's own rate limits are respected, and an image that has to wait is retried rather than marked as failed.
My run stopped and says the limit was reached. What now?
That is your monthly spending limit doing its job. The images that were done are done, the rest are still queued, and nothing further has been charged. Go to Billing, raise the limit, and the run continues from where it paused. If you would rather stop there, do nothing at all.
Does it work on collection images too?
Yes. Resize Collections handles collection images with the same modes, the same preview and the same undo as products. A collection has a single image, so a collection run is usually a short one.
Will my variant images still work?
Yes. When an image belongs to a variant, Miko re-points that variant at the resized version, so the variant keeps its picture and the product page behaves exactly as before.
Is my data safe?
Miko asks for products only. It never reads your customers or your orders. Backed-up originals are held for 30 days, are reachable only by your own store, and are deleted when you uninstall. See our Privacy Policy for the full detail.
Where do I find the app?
From your Shopify admin, go to Apps → Miko Bulk Image Resizer. The Overview screen is the default view when you open it.
