How to create IMAGE thumbnails

[Mark34198358cxrp]

Howdy,

This ought to be a painfully simple problem and I'm sure there's a solution somewhere... if anyone has wisdom, please share! 

1 - I have lots of photos

2 - I'd like to generate a bunch of square thumbnails, one for each

Yeah.  That's it.  As usual, the Internet has proven useless.  No matter what I search for in terms of generating IMAGE thumbnails, all results (even if I add "-youtube" or "-video") are for video thumbnails.

Any tips - including unrelated freeware, etc., are much appreciated.  What I do *not* want to do and am already perfectly capable of is opening each image, one at a time, reducing its dimensions, and cropping a square out of it.  That seems needlessly burdensome in this day and age.  

Thanks in advance for any help!

Mark

Do you have access to Photoshop? It sounds like you're looking for Image Processor (File > Scripts > Image Processor...) where you can process a batch to save at the desired size and as a JPEG, PSD, or TIFF:
