UBot html Template Engine

[cptnmacro 0]

I'm reworking an existing bot and am trying to create an html templating engine. For the most part I think I've got a way to handle it with the exception of images. The issue with the images is that there are 4 potential image sizes that may be needed in different templates, and the number of available images will vary per record. Here's a simple example of what I mean:

 

The first image may be 350px in the template, but the remaining ones would need to be thumbnails at 75px. Since the number of images in each record varies, I can't simly use <img src="[img1] width="350"><br><img src="[img2] width="75"> ><img src="[img3] width="75"> ><img src="[img4] width="75"> ><img src="[img5] width="75"> because if there are only 3 images in the record I'll end up with broken images in the html.

 

I'm thinking that I use something like [img1_350] in the html and have that be replaced with the actual code image code and of <img src=[img1] width="350"> if the proper field in the record contains .jpg.

 

I think this will work, but I'm not in love with it so I'm open to any ideas. Any help is appreciated.
