I got tons of PSDs I need to resize 3 times, saving them as PNG and possibly giving them a prefix in the name.
For example, I have this FINALPIC.psd which is 2000x2000, 300dpi. From this PSD I need to produce a HD-FINALPIC.png, full resolution, a LD-FINALPIC.png (800px as longer side) and a ICO-FINALPIC.png (150px as longer side).
It can process all of your different sets in one go by setting up all 3 process "sets" on step three using the + symbol on the left hand side, including fit image resize and file naming. I'd avoid using period characters in the filename and reserve them for the extension.
