Increasing height on Xart frames

[Vilfort]

Hi there.

I have this problem. I can't seem to get the Xart frames to be higher than 256 pixels. I tried messing around with some of the script files to make it create images that were 400 pixels high in the game, but they just dissapear if I do so.

Basically, what I need is to make it accept images that have a height of 400 pixels in the game and have them implemented. Works fine aslong as my images are only 256 pixels high.

Already tried DiscordArt, but really really dont like it much. Any help would be appreciated
