I need to install a sandboxed solution to my site (SPWeb). However I am not a site collection administrator, and therefore cannot access the solution gallery that exists at the site collection level. I am a site (SPWeb) administrator though. How can I deploy my solution on the site (SPWeb) that I am admin of? Or do I have to ask the site collection admin to upload my .wsp to the site solution gallery for me?
You'll need to ask a Site Collection Admin to upload it for you if you don't have the right permission.
