You need to set up an account on something like photobucket.com and download the pics there. Once you download them there will be four options to chose from I pick the bottom one, copy then paste and thats it.
when you post a thread or a reply, click the little paper clip and attach photos directly to the thread they i believe should be smaller than 976.6kb
