Reply: Power of Two Texture isn't Power of Two?

Almost certain my texture's a .png, or at least something common like .png or .jpg.

I saved my file as a .png (mentioned above), so I don't think there's a wrong name involved.

The file's called rosie_HuntersPursuitCredits, and the closest things to a matching name are the four interior names, which are rosie_HuntersPursuit with a number from 1-4 at the end. (No spaces. Right after the "t".)

A few things I've noticed can cause some issues:

- Weird formats like B/W or grayscale images
- Having PNGs named .jpg or vice versa
- Two textures with the same name in the same dir -- uncommon

Any of these the issue?

I'm trying to import a custom texture into one of my Constructor albums, and I'm getting an error message saying that the dimensions of my texture aren't a power of two. However, the dimensions of my texture are 512x256.
I'm quite stuck on what to do. Does anyone have any suggestions?
