Some linked images not working in HTML - php

Question

I have PHP code that generates HTML code which makes a grid of images. The images are taken from links that are generated for each new image, I also add 133x100 at the end of the image link to resize it on the page. My problem is that a seemingly random selection of images won't display, and I just get a broken image symbol. For example:
This is a link to an image that is generated on my page and is displayed.
This is a link to an image that will not be displayed.
I am only allowed to post 2 links, but removing the %20.%20/133x100 from the end of the last link will show what the picture should be.
Here is the part of the code for the image source:
function display_images(){
//This cycles through each image and displays it as HTML
while($row = $item->fetch()){
Echo "`<img src= '$link[Image_Link] . /133x100' />`"
}
}
It is then called here in a class which puts the images in a grid:
<ul class="rig columns-4">
<?php
display_images();
?>
</ul>
Seemingly about every 2/20 images won't work, and seeing all the links are in the same format, I don't understand why they won't work, and it just seems random.
EDIT: I have noticed that the links that work have 62fx62f at the end of them before the added %20.%20/133x100. If I add it to the raw link in the right place, it makes the image work. But using that generated link, the image still won't load on the page. So using a link with a working image will not work on the page. (This is the same with the raw link without %20.%20/133x100, that links to an image but also won't work on the website)

Answer 1

When visiting the links, the urls look like this:
http://www.example.com/image/randomcharacters%20.%20/133x100
The links work without the %20.%20 at the right dimensions, like so:
http://www.example.com/image/randomcharacters/133x100
This leads me to believe that it may work if you try using the following for the image source instead:
<img src= '$link[Image_Link]/133x100' />
The full code would look like this, for the while function:
while($row = $item->fetch()){
echo "<img src= '" . $link['Image_Link'] . "/133x100' />";
}

Answer 2

I am not aware of steamcommunity much but from the looks of it, i think you should try this.
Instead of putting
. /133x100
Use
/133fx100f
So your URLs would be
while($row = $item->fetch()){
echo "<img src= '" . $link['Image_Link'] . "/133fx100f' />";
}
Just did some trial and error and found out. No explanations for this though!!
