You can use any online image uploading site. I personally use
http://min.us/It is very friendly and uploading is very easy. There is even the option to drag & drop your file. After that you just share with me the URL to the link and I shall be on top of it.
By the way, just to throw a curve ball into your discussion, I think that although computers are part of the mix they shouldn't be part of the logo. This comes from projecting a specific feel that computer kind of take away from.
Just some thoughts.
