Resizing without losing content

[Ultimate]

Hello!

Rather easy yet complicated question. How would I resize, for example, a tileset that I've found without losing anything? I've extracted some large 3d isometric pictures but when I go to import them, the images don't wrap-around, rpgmaker just cuts them off once it gets past a certain width. i.e. if you tried to important a PNG from a digital camera, it would cut off a bunch of the image and not line up properly.

Example: I have this 400 x 400 png image





I need it to automatically convert to a 32 x 1300 png image so that the image can easily be pieced together within RPGmaker.














Any ideas or suggestions would be awesome! You guys are the best!

a tileset width has to be fixed, the tile size is 32x32 and the default width is 8 tiles which is a width of 264 pixels, although the height can be infinite, so every time you want to extend it another height of 1 tile just add 32 pixels to the height

Not what I mean. I've got some pictures more or less that I want to use as tilesets. The pics are, for example, 1000 pixels by 1000 pixels. The height is a non-issue. How do I convert these pictures into tilesets without losing anything? Without manually cutting and pasting every 32 tiles and dropping that cut underneath the first cut.
