How can I transfer iPhotos to a picture folder?
I've got hundreds of iPhotos on my Mac mini running Monterey but I want them stored as jpg or jpeg files in a Pictures folder. At present I can't drag and drop an iPhoto, nor will it allow me to add an iPhoto to an email, so they're absolutely useless as far as sending to family members, proof of identity etc. I've done this conversion before but forgotten how to do it. As an example I've taken some selfies on my iPhone as part of a verification process for opening an account. They provide the link to upload these, but I can't drag and drop the iPhoto concerned, nor can I attach I, t as iPhoto files do not appear under my Finder window. Can anyone help please?
