what you can do is go to:
http://photobucket.com/ you have to register,but that's free..
then upload your pictures to your album in photobucket,no matter what size they are...
after they are uploaded,photobucket put's "tag's" under each picture,4 different tag's.
click on the one that say's: IMG code,it will copie that automaticly,then go to the post your writing,and right click where in the post you want the picture to show up,and paste...
very easy to do,that way you can support all the parts of your post with pictures,lets say,you start of saying:"here's my bike stock",well press enter after that line,goto photobucket,get ur IMG code for ur picture of the stock bike,and paste it in the post....
then u can continue with ur story,and lets say you type"my bike after im done welding",do the same thing,IMG code with the corresponding picture....
that way it shows up in the post as you are explaining ur project etc.
good luck,hope to see some pictures...
