If you try to post them straight from your computer, you will have to resize them in order to meet the maximum size requirements of the site. I use photobucket.com to handle my pictures. I make a an album name and then upload the pictures to that album. Once the pictures are saved to the album you can click on IMG address under the picture and copy that location. Then in your post paste the IMG address and it will show up in the actual post. I always do a preview before submitting to make sure I got everything right.
If this sounds too cumbersome, you can google for a jpeg resizer and download the program and use that.
Max size of a jpeg is 73.2 KB and 450 width and 450 height
Photobucket allows for much larger pictures to be used, which is why I prefer that source. Hope this helps some. I am sure some other guys can voice some help and ideas.
