Photo resolution?

[steven]

This is an MS program and hubby doesn't want to install it on here.

What I'm having trouble with is that I tell the resizer to make the pic 800 pixels by whatever wide, but I can't tell it I want a file size of 100kb. Not directly anyway. I have to use a quality slide bar thingy that doesn't tell me how big the file is until after its doesn the saving. Stupid 'puters. They only do whatever you tell tem too. (I'm gonna have to get graphic converter again aren't I . )

Hi there

I wasnt aware you used a mac

Have you tried uploading any photos to the forum yet? maybe give it a crack and see what happens

Not knowing how big the file is because the computer itself doesn't know, until you actually tell it to save the image.

JPG compression used in photos is what is called 'lossy' compression - in order to achieve small file sizes, information has to be permanently and irrecoverably removed from the picture.

Since every picture compresses differently, it's not really possible to predict the file size ahead of time - the only way to do it is to run the compression algorithm...which takes just the same amount of time as some sort of 'previewing' option.

If your 'preview' option was aiming for a target size, you'd need to run a whole stack of possible sizes to gradually narrow down to the desired size, which is computationally intensive and would make for a slow preview option.

The technique that I've found works well enough for me is to resize pictures so that the longest side of the pic is between 10 - 15cm, at a resolution of 96dpi. This will generally give a pic somewhere between 30-100k.

Thanks Splinter. That's kinda understandable. I'lll just muddle on then.

Watson, What did you do? Does that mean my crack didn't work?

[tea lady]

Its alright Watson. I re Read my post. That is much better.

Too much time on my hands
I used to use Mac Image Resizer.....a freebie download......but since the upgrade....nothing.

I've used the text colour trick on some older posts, but wasn't sure (and still not sure) how they behaved when quoted. Archived material seems to be plain black on white.

With so many optional skins, hidden text probably isn't always hidden.

Looked good small, looked good when clicked on.

Keep doing what you did.
