When adding pictures to a thread, after you add a picture, if possible, hit the [ENTER] key or arrow key twice before adding the next pictures and what this will do is FORCE all your pictures to LINE-UP in a linear or straight line.
Here's a screenshot of your image code BEFORE I edited your post.
Here's a screenshot of our image code AFTER I edited your post and simply hit the [ENTER] key after each picture to force the next line of code to go downward.
Lots of our members do this, that is add all their pictures via TapaTalk without hitting the enter or arrow key twice after adding a picture so you're not the only one. I just know for the rest of history, a collection of pictures will DISPLAY better on all devices if they are forced to display in a linear manner.
