Unsolved Resizing images from URL

[lmx]

Hello,

How do I resize an image that has been inserted into a post using its URL? Either using percentage or using width definition (e.g., 500px). Thank you.

@lmx Good question. I am unsure whether ACP->Settings->Uploads affects url images. I think it does but been a while since I tweaked those knobs....

Have you tried/tested any of those that relate to images?
