you cannot “upload” any panos to ivrpa site, but IVRPA members can embed a GSV pano in a panoramas post which will appear on their profile and in sidebars etc like so
go to share>embed in your GSV pano and copy the src=”” value from the iframe code, it will look something like this –
https://www.google.com/maps/embed?pb=!4v1528786033433!6m8!1m7!1sCAoSLEFGMVFpcFBjY1V4WVA5T1U2Ym94cW5rMFY5OFRic0xDQzFBemJZNFc1a0lx!2m2!1d38.868021324004815!2d1.1965145740468555!3f0!4f0!5f0.7820865974627469
paste this value into the pano url field in your new panoramas post, also make sure to upload a good quality 1600×800 preview image which will be used for thumbnails etc
and see this post for more info on posting panos here –

here is the GSV pano from above, this was just a oneshot 360 camera snapshot, i don’t post any of my own high quality work on google so mo own posts on ivrpa site are hosted elsewhere
thanks
