I just posted my first band interview with a bunch of pics.
https://sh.itjust.works/post/63544454

I’m pretty sure my graphics, while definitely not hi-rez, are too big. I’m choking the system when I upload them, and they don’t render during page view very well either.

I’m just taking pics with my crappy cell phone.
I upload them by opening the pic in MS Paint, select all, copy, and then paste it directly into the post.

Just given the results I’ve had so far, and my intent to post a LOT more pics, perhaps I should tune this process up.

How would you do it?

    • Download and install GIMP on your computer
    • Download your images to your computer from your phone
    • Open your images in GIMP (you can mass-open a whole lot of them at once from your file manager)
    • Scale them down if necessary
    • Export them as WebP and/or JPEG, one by one ** Check how big WebP files get when you save them as lossless; save them as lossy only if lossless image files are too big ** If you go for JPEG, try 100% quality first, and don’t go below 90%
    • Directly upload these files to Lemmy (that is, I myself, in my personal position, being me and all, wouldn’t necessarily do that on Lemmy)

    Full-color photography isn’t so efficient as .png, so you might want to use .jpg or try converting to .webp somehow*. Even the original photos from your camera might be better than what you’re doing with paint which is likely just increasing data for no benefit.

    If you stay with .png (makes more sense for screenshots/text) it'd help to reduce data

    For .png especially, color reduction (crushing) if it doesn’t destroy your image, which will greatly depend on content.

    With G’MIC (usable via Krita, GIMP) a quick way to do this is a filter called ordered dithering which at the max (16 colors) takes it from ~16M possible colors to just 4096. You don’t need to go this aggressive, but it’s an option.

    Posterization is a simple way as well.

    Downscaling or cropping could help too, or for the future changing your camera settings down a size or two.

    Also, image optimizers can help further (the one I use has multiple forms of compression, it works on JPGs too but I think it does more for PNGs. I don’t think it’s on Windows though). Some of this is stripping metadata, which might be a good idea if you have that (unless you could turn it off in settings too?).

    * my instance does this by default, which is kind of annoying when I did optimize my image and everything (annoying because the lossy .webp has ugly blocks)

      Thanks.

      I do use an advanced camera app called ProCamX, because the default Android Camera app was was modifying my pics. I’m sure it has all the settings I need.
      I guess I should start there. Learn to use my camera.

      As for the PNGs, that’s what you get when you paste a graphic into a post. It makes it a PNG. No choices there.

        Don’t paste then? It should take whatever file you choose via file manager (on Lemmy it’s image>browse when creating a post, image icon in comment box etc).

    Final comment in the chain: https://sh.itjust.works/post/18680803/12480662

    I came across these discussion threads in the Lemmy and Pict-rs source code:

    It seems like automatic image compression might be something which could be configured in the pict-rs settings. Would one of the admins be able to chime in on the feasibility of this?

      Um … my other main instance is eviltoast.org, and … well, I think my posts forced the admin to implement those very things. If we don’t have the knowledge here, I could ask him.
