BLOG TROUBLES

I am trying to switch this over to tumblr but i can't figure the fuck out how to uplod many photo's at once. in blogger when your in the HardDrive window you can hold shift and highlight many files at once. Tumblr doesnt let you do that. if its not an option than im staying with blogger. anyhelp? anybody!? if the comment/message me section doesnt work email me at chance africa at hot mail dot com.Thanks.(also can i use the import/export feature to switch over? how does that work?)
