Allow to upload only images

As per title.

Do you have or can make security options to allow only images (we can specify which images like only – JPG JPEG GIF PNG) to be uploaded (maybe by adding deny allow values in htaccess for specific images allowed to be uploaded). All other files including scripts, php, ELF, binaries, css, js, htaccess, etc. are disabled.

– There must be also security check “getimagesize” to validate if this is image or not, then delete the file if this is not picture

– malware/virus scan of uploaded images on the go

– other security options for image related uploads

Thanks
