I’m looking for a gallery particle, that displays all preview images in the same width and height, regardless of what size the images have. Which gallery particle has that option? I tried several for now and I somehow didn’t get it to work.
Image resizing feature is not supported, you need to custom the image sizes using tools like photoshop and present the image as thumbnail item for the gallery. This feature already discussed here.
Note: You can use Phoca Gallery https://www.phoca.cz/phocagallery for the similar feature.
