If you wanna upload multiple photos or suppose multiple documents and if the option is missing then don’t worry as it’s a simple issue and resolution too.
Upload multiple photos is missing in upload dialog box
Upload Multiple Files is missing when you don't have any local Office clients installed. Here's the list of requirements to see that option:
1. The 32 bit version of Internet Explorer. The 64 bit version does not support it and neither do other, non IE, browsers.
2. The STSUpld.UploadCtl IE add-in must be enabled.
3. Office 2003 /Office 2007 / Office 2010 / Office 2013 or newer on the client
4. Client integration will need to be enabled for the web app.
Why it's required? Here is the reason- There is an ActiveX control that is used to support multiple file uploading - that ActiveX control is installed with office.
That’s it – once you install any of the client (i.e. any office version as listed above – step#3) then your issue will be resolved.
