Hi, zonkerzebra, you’ll have to do that before uploading the image. you’ll have to upload a square version for the Gallery image. You can use GIMP or PS or any kind of image manipuation Software for that or re-render the part you want to be seen in the Gallery with Border Render. ‘Inside’ you can then of course also upload the full version, just use the square one as the ‘main’ picture, that shows up in the Gallery.
