This is a simple site that allows you to create your own RO Login Background. It's now fully functional. With this tool, you can upload any image of your choice and select the desired area to be cropped. You can also adjust the aspect ratio to your liking.
Features:
Support for t_login.jpg output for newer clients
Multiple quantization algorithms for 8-bit mode (NeuQuant, Median Cut, K-Means, etc.)
Optional noise dithering to improve quality of images with blending showed on the RO Client
Output Options:
Default output (24-bit BMP): Produces high quality images
8-bit BMP: Reduces the final output size significantly (with some quality loss)
t_login.jpg: For modern clients that support JPEG backgrounds
Tool URL: FroggoCutter (sapitosucio.github.io)
The files generated have the following format: t_¹è°æX-Y.bmp, said files are compressed into a .zip file, then it's downloaded.
Do remember those BMPs files should be placed on:
data\texture\À¯ÀúÀÎÅÍÆäÀ̽º
Btw everything is done locally, nothing is uploaded.

Known Issues:
When you try to slice a big image (>2000px) and 8Bit is selected, the browser may lock itself for a few seconds (❁´◡`❁)
Froggo tip of the day: Use big images(>2000px), upscale them or something and then, slice it, the final result is quite gucci
