When I upload a png image it's always converted into a jpg? How to stop that?

so in stead of this

const imagePath = "${folder}/${uniqueName}-${sizeName}.jpg";

const imagePath = "${folder}/${uniqueName}-${sizeName}.jpg";

const imagePath = "${folder}/${uniqueName}-${sizeName}.jpg";

const imagePath = "${folder}/${uniqueName}-${sizeName}.jpg";

something like:

const originalExtension = image.originalname.split('.').pop().toLowerCase();
        const validExtensions = ['jpg', 'jpeg', 'png', 'webp', 'gif', 'tiff'];
        const extension = validExtensions.includes(originalExtension) ? originalExtension : 'jpg';

const originalExtension = image.originalname.split('.').pop().toLowerCase();
        const validExtensions = ['jpg', 'jpeg', 'png', 'webp', 'gif', 'tiff'];
        const extension = validExtensions.includes(originalExtension) ? originalExtension : 'jpg';

const originalExtension = image.originalname.split('.').pop().toLowerCase();
        const validExtensions = ['jpg', 'jpeg', 'png', 'webp', 'gif', 'tiff'];
        const extension = validExtensions.includes(originalExtension) ? originalExtension : 'jpg';

const originalExtension = image.originalname.split('.').pop().toLowerCase();
        const validExtensions = ['jpg', 'jpeg', 'png', 'webp', 'gif', 'tiff'];
        const extension = validExtensions.includes(originalExtension) ? originalExtension : 'jpg';

so we can use:

const imagePath =  "${folder}/${uniqueName}-${sizeName}.${extension}";

const imagePath = "${folder}/${uniqueName}-${sizeName}.${extension}";

const imagePath =  "${folder}/${uniqueName}-${sizeName}.${extension}";

const imagePath = "${folder}/${uniqueName}-${sizeName}.${extension}";

talking about images — maybe the manifest could save images in their original size as well, so as not to use the file property?

@MURO

what format of image do you need to generate ? PNGs ? What is your pain point ? Manifest is using Sharp behind the scenes https://github.com/lovell/sharp so we could imagine other formats. We went for JPG to keep things simple first
