Look for the bot you want to use and find an image for it. It could be any format.

Change the format to a PNG if it isn't one already. You can do this by right clicking the image file and pressing edit. This will bring it into MSPaint. Click file and press save as and then put PNG. After you have done that hover the mouse over the files and delete the one that isn't a PNG.

Drag and drop the files into the previews photo. To get into the preview photos, go into the game settings on Steam. It is above the workshop and store page tab. It looks like a gear. Click on it, go to manage, and press browse files. After that click previews. Drag your files into it and if it already has a preview photo, it will ask if you want to replace it. Click yes and it will appear into your game. If the bot doesn't have a preview then it will become the preview once you drag it.

If not done it will not appear as the preview. I believe the way you can tell it is the preview is when it moves into the middle of the folder.
