Tileset Error

[PyRRamid]

I've created a 320x320 pixels picture to try if making a tileset will work. The TilesetM.bmp file has transparent upper left corner, three couloured tiles and all the others are black. I did everything ok and when I pressed "BUILD" an Error Message appeared saying :

Error! Can't open file "D:\Mladen\Jazz Jackrabbit\Jazz Jackrabbit 2\Tiles\TilesetM.bmp"
Done - 0 successfull build(s), 1 error(s)

Does anyone else has already had this problem and does anyone know how can I solve it?

This is the tileset (I made it using photoshop) :

The corner is transparent (dunno why it appears white)

At a guess, whatever program you are using to edit TilesetM.bmp is still "holding on" to the file, thus not allowing JCS to access it.

I thought of that, so I closed Photoshop. IT didn't work.
Thanks, anyway.

I got my problem solved. Actually, my image wasn't 8bit. Violet helped me.

When I start Photoshop, I select 8bit, and when I try to save it, 8bit radio button is grayed out. I don't know how can I fix this, maybe I'll use another picture editor, but, I got my main problem solved.

Sorry for disturbing,

if anyone knows how to save 8bit .bmp images in Photoshop, post your ideas.

Thank You in advance,

Pyramid.

If you're not too bothered by the palette you could use TilesetPal to reduce it for you.

Save as a PNG ir wutever and open with MSpaint? Mspaint is awsome. So 256 color saveble.

Also, just so you know, 8-bit is 256 colors.
