although I'm not sure there is one that can 'batch' process photos.
About the limitation on 'size', or quantity.... the main reason for that restriction on this board is to not 'break' the display format. And the truth is... I'm not really sure where that 'limit' is reached, I only know that where we are now set on a size limit it does NOT break the default display format. There is a limit.
I'll ask Ramsrule about it, he would know far better than I would. Maybe, (big MAYBE), we could increase that somewhat to allow for bigger photos to be allowed. - JamesJM
