Help with High Resolution Export

Hi guys,

I'm working on a comic book for the web (using Photoshop CS5) and I'm having trouble exporting it in a way that people can zoom in to read it. The original PS project has A LOT of resolution:
Height 43,18cm per width 27,94
resolution 1000 pixels/inch

Obviously I cannot export a JPEG with that kind of size/resolution...otherwise people will need an eternity to open such a large file.
Does anyone have any idea about a nice size/resolution for the web so that it's readable?

thanks in advance
 
Zoomify would be the perfect solution, but it generates 100mb sized files. That is not going to work for me.

Is the 100 mb size a limitation of your web host?

It's not generating a single 100 mb file. It's actually generating hundreds of small files which are stiched together to form the image. The end result is the ability for the user to zoom into the image with being subjected to long load times. The small file sizes load rather quickly. Quite a clever approach by the propeller heads that wrote the code for this.

To see something similar have a look at Gigapan.

These are massive photgraphic images - that load very quickly.
 
I'll be posting it on my blog. I cannot upload folders there, only individual pictures, videos and links. I've pondered creating an account in one of these free web hosting sites, but most of them only grant you a very small amount of space (the biggest I've seen offered 250mb, which would allow me to do only 2 pages!). There has to be other way. For instance, check out these comic book pages bellow. As you can see you may magnify and read perfectly.

A little reverse engineering.

For web based work it's fairly common to work at 72ppi. Of course for print work the resolution is much higher. It sounds like you're converting a print project for the web. At any rate 1000 ppi is overkill. Experiment and see if you can rescale your document with losing too much information.
 
Thanks, bud. I'll give it a go to see how it turns out. I thought I'd work with a massive resolution because I thought it would be easy to downsize.

For 'web' work, the concept of ppi/dpi/whatever-per-inch/cm/mm is useless... for computer displays it is only the pixel dimension on the display, and 'how much' of the area
you want to 'fill'.

What one needs to think of is the 'screen' that most of the intended audience will use, or perhaps a bit bigger, and output the web directed media to that resolution.

Screen resolutions have moved from 640x480, 800x600, 1024x768, with variations, few screens that most people use, are in the category of even 1920x1080... ok, maybe now more people are using their video flat panels more...

But the main thing is any image beyond 1024x768, and even then, will be 'windowed', and the user will have to scroll through the image. The exception being when someone uses a tool that allows for 'size to fit', and uses the whole screen of their display (mostly for video presentations... or power point, or keynote...)

So, for the moment a max width of 2000 and a max height of 1200, should allow someone to view the material, with some scrolling, or use one of the 'autosizing' features of their browser.
 
Using bitmaps for web work and needing to zoom in is just a bad idea. That's what vector graphics is for. Particularily for comic books and graphic novels. Bitmaps are resolution dependant. Vectors are resolution independant.
