    Dynamic image size generator▲21

    Hi, Firstly, the link to the tool - https://github.com/DrRoach/DynamicImage I created a dynamic image sizing tool that allows images of any size to be generated on the fly. It's aims are as follows: a) Allow users of sites to upload images of any size without the site owner having to worry about their dimensions or having to resize them. b) Reduce load times for sites as images can be stored on their own dedicated server and be served in milliseconds. I'd love to hear some feedback as to what you think and whether you'd consider using this tool and if not, why not? All…

    An all-in-one image crop/split/collage tool (no uploads, no watermark)▲7

    Hi HN, I rebuilt my side project into a small “all-in-one” image toolbox: https://imagesplitter.tools The part I’m most proud of (and personally use the most) is the collage workflow: 1. Grid collage (templates + merge cells for “one big + many small” layouts) 2. Long-image stitching (great for screenshots / step-by-step guides / chat logs) 3. Freeform collage (DIY your own grid layout — split/merge cells however you want — then apply that layout to the grid collage) My motivation was pretty simple: I kept bouncing between different sites for basic image chores, and…
