Get a photobucket.com account. You can upload and resize your pictures there.
Then copy the 'img' code of your pics from photobucket by clicking on the "img" box in the 'sharelinks' area on the right of the photobucket page.
Then in your reply dialogue box on this forum, you should only have to do a right click paste to insert the img code in your post. Click the preview button on the lower right to make sure your post looks like you want it to.
I'm not an expert though, by any means. Anyone have a simpler way? Prolly are a few lol.
