Manufacturer images
The sizes generated for brand logos, used wherever a manufacturer or brand is displayed on the storefront.
Brand logos vary widely in shape, so it is worth checking a few brands after changing these sizes to confirm that wide and tall logos both still display well.
How to Configure Manufacturer Image Sizes
Select the store you would like to update
Click on Manage Store Settings underneath Settings
Open Image Sizes
Open the Manufacturer images section
Set the sizes you want generated
Save your changes
Changing these sizes affects images generated from that point on. Images already uploaded keep the sizes they were generated with.
