(Requesting sticky, please.)
I am using
Adobe Photoshop CS 8 for these instructions:
Open your finished
2560x512 image. Make sure that your background layer is transparent. Up top click on
Layer and then choose
Merge Visible.
Choose your
Slice tool (or hit K on your keyboard). Right click over your image and choose
Promote to User Slice. Right click once more over your image and choose
Divide Slice. Put a tick in the box for
Divide Vertically Into and you want
5 slices across, evenly spaced. (Put a tick in the box for Preview if you want, although not needed.) Click Ok.
Go up to
File and choose
Save for Web. This will open an Image Ready window. On the right side of that window from the Preset dropdown menu choose
PNG-24 and put a tick in the box for
Transparency. On the left hand side,
be sure that the Slice Select Tool is chosen. Click Save. (This assumes you've already created an empty folder to place the images.) Click Save once more and it will save all 5 sliced images into a subfolder named "images".
You will need the image converter
located here on WoWI. Drop the exe file into the folder where your sliced images are located. Now (with your mouse) drag one png file at a time over the top of the BLP2PNG.exe file and it will convert it to a blp file. Do that with your remaining png files and you're done converting your images
