If you're using GraphicConverter then you probably want to use the scale option under the size item of the picture menu. This will let you specify both an output width and/or height and resolution. If the images are for screen display then obviously 72 dpi is all you need. If you want print output then 150 dpi would be an absolute minimum. I'd maybe do this in two stages. First just set the dpi of the image to what you want - this won't change the overall size of the image. Then proportionally resample/resize the image to whatever your maximum width/height settings are appropriate before saving them in whatever format is appropriate (it sounds like you'll be using JPEG).
I guess you could do this all in Rev provided it is capable of displaying images with the types of pixel dimensions you're talking about and you only want screen resolution images. You'd set the filename of an image object and query its formatted width and height. Then you'd rescale it to match your predetermined maximum dimensions. Finally you'd export a snapshot (which will be at 72 dpi) with your preferred level of JPEG compression. If you want more than screen resolution then you should export them without compression and take them back into GraphicConverter to change the resolution without resampling (resolution item of picture menu) and then save and compress them from there.
