polish README: images up top, full-width, custom value + standalone notes

- move all node screenshots above the description text, full-width (100%)
- note that Longest side accepts a typed custom value, not just the presets
- clarify Smart Batch Resize works standalone (no wiring needed, just folder + Run Batch)

 ### 📁 Smart Batch Resize

 Load **all images from a folder**, resize each one by longest side, and save into a subfolder. Build clean dataset filenames from a prefix, the original name, and/or a sequential counter — combined with an optional resolution suffix.
 
-Use this for **bulk preprocessing** — e.g. preparing a LoRA dataset from a folder of high-res images. The node always writes resized images to disk inside the input folder; connecting the outputs is optional.
+Use this for **bulk preprocessing** — e.g. preparing a LoRA dataset from a folder of high-res images. It works as a **standalone node**: it needs no upstream input and no downstream connection to do its job — drop it on the canvas, point it at a folder, hit **Run Batch**, and it reads, resizes, and saves everything itself. Connecting the `images`/`count` outputs is entirely optional, e.g. for previewing results.

 ### 📏 Smart Resolution Multiplier

 Multiply image dimensions by a factor and output the results as integers.
 
 SeedVR2 takes a single `resolution` INT (the longest side) — not a width and height separately. Standard math nodes give you a FLOAT or require multiple steps to get there. This node does it cleanly in one step: give it your image and a multiplier, and it outputs `width`, `height`, and `resolution` (longest side) ready to connect directly to SeedVR2's `resolution` input.
