Screenshots on steam workshop?

Need help in posting screenshot to my blueprints on the steam workshop. They are too big and i get an error message.

 

So the default screenshot image is .png. They are to large for Steam Workstop, they have a limit of 2meg per picture. Just open the .png in paint or a similar program and save them as a .jpg. that will make them small enough to import

 

OK it was that simple thanks so much.

 

If you take screenshots using the steam overlay, they are already made into high quality jpgs with a smaller footprint of around ~300-500k. There is very little visual loss (and honestly not many people will notice).

For blueprint extra images, they are more then adequate to get the item across.
