If you click File>Batch conversion you can just set the machine running and a few hours later you recover 10G of space. Just have

Hm... Not yet. Looked at it last night, took tips from Dougal too, in the ned I sent him the pic so he could try. If I crop vaste swathes of background I can redice by 1.5 kb!!...I'll have another go tonight.

But Dougal didn't get it... or even know he'd been sent it. ???

Dougal said that after cropping the image, adjusting the physical size and reducing the resolution (should have said pointless more than 72dpi for web use - or go direct to the number of dots required), the next thing would have to be being more aggressive with the JPEG compression by adjusting the "Save quality" slider to a lower number...

I'd thought the "sticky thread" ought to be kept clean and general, so sent a PM for the individual question...

Thanks Jema, the problem seems to be that it is.bmp so I'll try and change to .jpeg and try again. Can't upload as a bitmap, it seems.

.bmp files are quite big. When you 'save as' you have to change the extension. I don't believe the compresssion works on anything other than .jpg and .png, but not .bmp anyway, as far as I can see.

And you ended up reducing it from 30k to 831 bytes... !!!

JPEG, because of the compression, is an excellent format for photographic things, especially for web/email use.
With JPEG there IS always going to be some loss of quality compared to the uncompressed original - usually visible as jagged (sometimes coloured) edges when examined very closely. But you can choose how much compression to apply... and thus how much quality you can give up...

What are you trying to do? Quicktime, I think, is video viewing softwear, when does the message apear?

Mochyn, I think you have what is called a software conflict. This occurs when your pc is trying to be clever and think for you. It assumes that you want such and such, so uses a particular piece of software. Close down the video editing software, if needs be by using ctrl alt del together, then open IRFANVIEW, and use that.

If you look further back up this thread you can see I also had initial probs, but this is actually really easy to use!...When you get to the "save as" bit, a chunk springs up on the right, and that's where you size it down.
