Frequently Asked Questions
Can I resize only the detail page width?
Yes. Width-based resizing keeps the original ratio and calculates the height automatically.
What should I do with very tall images?
Resize the width first, then use the detail page splitter if the image is still too tall.
Is 860px always the correct width?
No. Recommended widths vary by marketplace and template. Check the actual upload screen before use.
