Trying to preload them using PreloadAsync and asset ID’s like “rbxgameasset://Images/Maxamillian” causes an error. There is a way to preload them (http://devforum.roblox.com/t/are-images-in-the-assets-folder-preloaded-automatically/25714/3?u=mrhistory) but it requires a lot of annoying and unnecessary manual work.
For example, to preload the image called Maxamillian, I first had to find it on the Develop page under Group Creations > Decals. Its ID on the website is 425078462. I then had to create a temporary ImageLabel somewhere and set it’s Image to “rbxassetid://425078462”. I then had to keep decrementing the ID by 1 until the image showed up. In this case, it showed up all the way at “rbxassetid://425078453”.
I need to repeat this process for every image I’ve uploaded in studio and wish to preload. PreloadAsync should absolutely be able to resolve “rbxgameasset://” links.
