Need help with right click resizing batch.

[Innomen]

Ok so I've seen this thread but I can't adapt the answers given to my situation.

I've created a batch file in my sendto folder:

I need to know what code to put into it to get it to resize selected images with the following options:



I would very much like someone to give me the code to put into the batch file to accomplish this. Thank you for your time

Context:
Essentially trying to replace this because it changed the file dates.

I take my photos with a 16megapixel phone camera but the majority of my images do not need that resolution. So as I sort them into their respective folders I want to be able to down size the ones that don't need max resolution by selecting them in the folder and right clicking and sending to the batch for IV to resize.

I want them basically to end up a third of the size as when they started, replace the original, and retain the date.

If there is a better way to make a jpg stop being 5meg I'm all for hearing it

Basically I think of this as a divide between photographic resolution and utilitarian resolution. Like portfolio vs twitter meme quality

I'm in win7 64 fwiw.

I'm looking for strategy advice as well as raw tech support on the construction of the command line and batch file.

If I was 100% sure this was the best set of settings I could probably hammer out the code myself but I kind of want to hear opinions also.

I am not too keen on writing batch scripts, I would do it from the Thumbnail viewer by selecting files, then pressing the "B" shortcut to launch the Batch dialog. Writing scripts, testing them, and modifying them for other tasks often takes longer than just opening IrfanView and doing the job in the usual way.

From the linked thread, using the /advancedbatch switch might be a solution for you.

Regarding image size, the trade-off between quality and size decreases rapidly towards the top end of the scale. If your primary target is images for the web, file size is far more critical than image quality. Some images can be compressed a lot more than others without much loss of quality.
