There is a button on the top area called readers rigs, click manage your gallery and then you fill out the form for the info then click on the browse button and look for the pics on your computer and open and click upload.
After you get the pics up, go back to the main area by clicking readers rigs again and find your gallery in the list and open it, Click on the pic you uploaded there are 4 #'s 1,2,3,4 these represent size of pic to view. I ususally use #2 open a pic and right click on it and select properties. in the window that pops up, highlight the URL in the middle and copy it (right click, select copy)
Then go to the post. It helps if you are doing multiple pics to have 2 windows open, one to the post, one to readers rigs... .
to be able to show you the code to use I have to use "*" inbetween the letters and stuff otherwise it won't show up for you. DO NOT Use the "*" symbols, they are nothing
<*img*src=(URL(Right click, and Paste))*/src*img>
The only place where there is a space is between the IMG and SRC. you have to use the < and > at the beg. and end and the forward slash after the URL.
If everything goes well, you can post a pic like this
<img src=https://www.turbodieselregister.com/user_gallery/sizeimage.php?&photoid=5696&width=2/src img>
