How Can I Add 더 많이 Than One Image At A Time???

Here's how 당신 do it:

당신 go to the file 당신 want (which would most likely be pictures)
당신 hold in the 'Ctrl' button while 당신 pick your pictures, then 당신 click ok, and 당신 can 업로드 up to 20 이미지 At a time.
But they all have the same description, name, etc. and the only way 당신 can change the name and stuff is to 편집 them after they're submitted.

Hope this helps!
