Compressing pictures

[BuFfY]

I am in the middle of making a powerpoint presentation that I need to put onto a CD and present 2moro. I have used a few pictures and I am scared that it will be too big to put on a CD or it will spaz out or something!

So I was wondering if anyone could tell me how to compress a picture, so that the size is smaller

Thanks so much!

Re-sizing maybe?? You could use compression programs, but not really needed, just use a smaller version of the pic.

Also, you will not be able to make a presentation bigger than a CD. I had a group project, with voiceover, images, fully automated, that was only 34MB or something.

A huge pic may slow the presentation down a bit tho, so just resize the images...

So 820 KB is ok?

Yeah I don't know too much about this stuff! And I really don't want anything to go terribly wrong because.... well... I have put a lot of effort into it!

820KB for what??

For slideshow, it will be absolutely fine, how many slides is this over?

For an image, much too big, you could drop that down a fair chunk.

So 820 KB is ok?

Yes - fine - as long as it's not a 386 machine.

Your images don't need to be bigger than say, 1200pixels wide if they are to be displayed at 100% in powerpoint

if you are enlarging them on screen - then they need to be bigger.

Turns out if you press the 'compress' button it compresses it!

So now the whole show is 750KB and it is going to be about 12 slides

Nothing at all to worry about, you shouldn't have any problems at all. My lecturers slides are all longer and larger than that.

Mind you, as BD said (he has the odd nugget of good info ) it does also depend what computer it is running on. I would assume that this is a uni presentation?? And of course would have powerpoint, etc, and would be a fairly modern machine....

Yeh everyone elses has worked fine!

I have to take my laptop in for another presentation so I can use mine if worst comes to worst!

Thanks so much for your help

CD's are good for about 700Mb - a ppt that big would take a week to present.

As an aside- if you want to compress photos for a Word doc, use a programme called Hypersnap. It is basically a whizz-bang screen dump programme, but it works a squillion times better than making bitmaps with
Paint, and you can insert good detail photos without pigging the memory (Word doc's tend to get corrupted when they get too big)

When giving presentations using Powerpoint, you find yourself at a point where you want the audience to focus on you, not the screen. Instead of trying to cover the projector with a book, lens cap, curtainsider or similar, simply press the B key on your computer. This stops the projector poking light out by way of making things black. Press B again to bring it back to life.

Note that this only works when Powerpoint is in Slide Show mode.

Thats interesting. I received an email of a bitmap satellite photo of the South Island yesterday. Brilliant photo but I couldn't figure out why it took so long to open. Then I had a look - 14.4MB!

So before sending it on I cast around the net and found ReaJPEG http://www.reasoft.com/products/reajpeg/ which did the job. Converted to JPEG and about 1MB file. 30 day free trial. I have no idea whether it is better than Hypersnap.

[What?]

Yeah, there's bound to be a few different programmes out there that do essentially the same thing. Hypersnap is the only one I know anything about, and people I know who use it rate it highly for user-friendliness. Got a feeling the base version is free, too.

yee gad boy, don't do bitmaps at approx 2MB for a 1024x768 screenshot. You lose a bit of the detail, but a jpeg is still plenty serviceable.

And yes.... documents can get corrupted easily... when you have 3 backups, you know you're asking for trouble, especially when you spend half your time making and using copies

As soon as you are done with a word doc, pdf it, much better for reading, transferring etc.

Just incase you want to know... I got 9/10 for the presentation! yay1!

So I am very happy with that!

Oh and thanks everyone for your help with compressing pictures! It is great to know I can go somewhere at like 1am to get answers about anything!

ROFLMAO!!! a slideshow too big for a CD!!! unless it had like half an hour of fullscreen video in hi-res you would be hard pushed to max out a CD...

you're just as bad as my mum, who got me to write 7mb onto a 700mb CD... i dont understand it, she was the one that lost my USB stick.
