Photo alignment problems, probably in php

My blog is creamofthecropcrochet.com
About a week ago I tried adding 2 thumbnail images next to each other with 2 spaces in between on the “Our Free Pattern Collections” page. When I hit the space bar the first time it was okay. When I hit the space bar the second time, it went under as if I had hit enter. I tried it again, and got the same thing, so I tried using only 1 space in between. It was okay until the image was inserted and it automatically went under the previous image.

Next I went to test an new page to see if it was just that page. I added an image, hit the space 2 times, and tried to add another image next to the first image and it just went right below.

I wanted to see how deep this problem was so I checked “Projects” tab. The same thing as before. Then I checked even deeper with a new post, and I got the same. Then I checked “Turban Newborn Hat Pattern” and got the same thing again.

I checked a post further back (Preemie Bee Flower Hat Pattern). That post was a bit different. I hit the space bar 2 times next to the large image, but then hit enter because an image wouldn’t have fit next to it. Then I added a thumbnail image and hit the space bar 1 time and it was as if I have hit enter, but I didn’t.

The “Turban Newborn Hat Pattern” and the “Preemie Bee Flower Hat Pattern” are different, because I hit the 1 space on the turban, and it went right under the image as if I had hit enter. On the bee it didn’t, it did what it was supposed to at first. The bee photo was last modified March 10, 2015. The turban photo was last modified 3 days ago.
From the looks of my testing, this happened in the past couple weeks at least, and not all of my blog is “infected”. Only the part that I mess with now.

A couple weeks ago I was testing some plugins…I have a feeling it might have something to do with that. I did delete the ones I didn’t like. I did deleted the ones that I still have and tested older pages again, and still have the problem. I noticed when I re installed my plugins that it went to the same setting I already had, so when I delete it, does it not really delete it? Because if I deleted it, then it would have been gone and I would have had to redo all of my settings. So something would have had to stuck around to “remember” my settings.

My really big question is if I install wordpress with my hosting again (I use bluehost), will I be installing a completely new blog or will it just replace what I already have? Would it fix the problem? Or what would it do?
I would really appreciate any help. Thank you.
