Q: Install El Capitan from SD card?
Is it possible to download the El Capitan installer to a SD card and then install the OS from it? Or should I just stick to using a USB drive to install the OS onto my computer? (This is on an IMac 8,1, running Snow Leopard. No PowerPc things & stuff on the computer)
iMac, Mac OS X (10.6.8)

Absolutely. Flash is flash.
Download from the App Store. Quite the installer if it tries to start. It will be in your Applications folder (Install OS X El Capitan.app)
This command will install onto an "Untitled" SD card that is formatted for Mac: extended journeled
sudo /Applications/Install\ OS\ X\ El\ Capitan.app/Contents/Resources/createinstallmedia --volume /Volumes/Untitled --applicationpath /Applications/Install\ OS\ X\ El\ Capitan.app --nointeraction
